The moment a child turns 18, many parents think the hardest part of raising them is over. What follows, however, is often something far more complicated, and far less discussed.
A generation of young adults is taking longer than ever to reach traditional markers of independence: finishing school, finding financial footing, establishing their own households. The number of young adults who live with their parents has risen steadily since 2000.
And the society they grew up in is vastly different from the one their parents experienced. It should come as no surprise, perhaps, that relationships between parents and their adult children are under greater strain than ever before.
What causes friction between parents and adult children? Which behaviors lead to an erosion of respect between the parties? That’s what this article is going to explore, in some depth.
Note: this article does not specifically cover neglect or abuse during childhood. Those things almost always lead to poor or non-existent relationships between parents and their adult children. The focus of this article is on behaviors that are present once the child reaches adulthood, and behaviors that can go both ways.
1. Being too defensive to reflect on their behaviors.
Nobody enjoys hearing that they’ve hurt someone they love. So, when that feedback arrives, the instinct to defend ourselves can feel almost automatic. We deny it, deflect it, or turn it back around on the other person.
The problem is that defensiveness, however understandable, completely shuts down any possibility of growth or repair.
For parents, this often shows up as an inability to hear how certain aspects of their parenting left a mark. When an adult child tries to express hurt, a defensive response—”I did the best I could,” or “You’re twisting what happened”—communicates that being seen as a good parent matters more than the actual relationship.
For adult children, defensiveness can be equally destructive. Refusing to acknowledge that your own behavior has caused hurt, or immediately counter-attacking with a list of past grievances, sends exactly the same message.
Over time, defensiveness trains the other person to stop trying. When someone has raised a concern three or four times and been met with denial every single time, they stop raising it. That withdrawal is an early sign that respect is starting to erode.
Letting your guard down enough to actually hear difficult feedback is hard. But it’s also one of the most powerful things you can do for any relationship you value.
2. Being too prideful to apologize.
A genuine apology requires vulnerability, and pride is fundamentally at war with vulnerability. Saying “I was wrong” means admitting fallibility, and for many people, that feels far more dangerous than it actually is.
Many parents were raised in a generation where apologizing to a child was seen as undermining authority. The belief was that admitting fault would somehow weaken the parental role, cause children to lose respect, or open the door to chaos. So, the habit of never apologizing became deeply ingrained, and it followed them right into their children’s adulthood.
Adult children aren’t always innocent in this regard. For them, apologizing to a parent can feel like conceding defeat, or worse, like handing the parent validation for every criticism they’ve ever made.
So instead of saying sorry, both sides dig in. And the wound that a simple apology might have closed sits open for years. Sometimes decades.
A refusal to apologize doesn’t just fail to fix the problem; it signals that the other person isn’t worthy of a resolution. The other person feels that. They remember it. And each time it happens, a small amount of respect disappears.
You’re allowed to say sorry, even when it’s hard. Especially when it’s hard. An apology is one of the clearest signals you can send that this relationship means something to you.
3. Being too afraid to admit their flaws.
Fear and pride can look identical from the outside, but they feel very different on the inside. While pride says, “I won’t admit this,” fear says, “I can’t because the consequences would be too terrible.” Distinguishing the two matters, because they require different responses.
For parents, admitting a flaw can feel like admitting they failed at the most important job of their lives. Many parents carry an enormous amount of guilt already, and the fear is that acknowledging even one mistake will confirm every fear they’ve had about themselves as parents, or give their child permission to blame them for everything that’s ever gone wrong.
Adult children face a different version of this. Admitting a flaw to a parent can feel like regressing back to childhood, like handing over power they’ve worked hard to claim for themselves. That vulnerability can feel threatening, particularly if the relationship has a history of criticism or conditional approval.
What both sides miss is that this fear creates something arguably worse than the flaw itself: a relationship built on performance. When neither person is being real, what you have isn’t an authentic connection; it’s a careful presentation of who each person wants the other to believe they are. Respect cannot survive that kind of inauthenticity for long.
Many people find that admitting a flaw actually strengthens a relationship rather than damaging it. Realness is disarming. And more often than not, the other person was already aware of the flaw; they were just waiting to see if you’d ever acknowledge it.
4. Refusing to acknowledge that the relationship needs to evolve.
Among all the reasons respect erodes between parents and adult children, this one is perhaps the least discussed. And yet, it is extraordinarily common.
Parents who continue relating to their adult child as though they’re still ten years old aren’t doing so out of malice. Often, it comes from love, from habit, or from the deep emotional memory of who that child once was.
But the effect is deeply frustrating for an adult who has built a career, formed their own family, and developed their own values and judgment. Being treated as though your autonomy is still provisional is disrespectful, even if it’s not intended that way.
Adult children aren’t always blameless here. Continuing to see parents only through the lens of who they were—perhaps controlling, or absent, or critical—rather than recognizing them as complex people who are also aging, changing, and possibly trying to do better, is equally limiting.
Young adults who come to see their parents as full human beings, rather than simply as parents, may find that relationship more satisfying over time.
The dynamic between parents and adult children must shift from one based on authority and dependency toward one based on mutual respect between two or more adults. When either side clings to the old template—the controlling parent or the defensive, rebellious adult child—friction is inevitable.
5. Constant unsolicited advice and criticism.
Few things erode respect faster than feeling like you’re constantly being evaluated and found lacking. And yet both parents and adult children can fall into this pattern without fully realizing how often they’re doing it.
When parents regularly offer opinions on their adult child’s career choices, financial decisions, parenting approach, or relationship—without being asked—the underlying message lands as “I don’t trust your judgment.”
Even when the advice comes from a place of love and concern, the relentlessness of it communicates something else entirely. There’s a meaningful difference between advice offered once, warmly and with care, and advice that appears every single time you speak.
Adult children do this, too. Regularly criticizing a parent’s health habits, political views, technology struggles, or lifestyle choices sends the exact same message in reverse. Parents are fully entitled to live their lives according to their own values, and treating them as projects to be corrected is just as disrespectful.
Dr. Laurence Steinberg, a leading expert on parent-adult child relationships, makes the point well in a 2023 interview: “unless you’re asked for it, keep your opinion to yourself. Except in those situations where you think that the consequences are going to be very, very severe and irreversible.”
The reason isn’t that your perspective doesn’t matter; it’s that autonomy is deeply important to adults of all ages, and having that autonomy constantly questioned is exhausting.
6. Weaponizing the past against each other.
Addressing past hurt is healthy. Using it as ammunition is something else entirely.
Parents sometimes bring up every sacrifice made, every dollar spent, every hardship they endured—not to share their experience, but to enforce guilt and secure compliance.
“After everything I’ve done for you” is rarely the beginning of a conversation. More often, it’s a tactic, consciously or not, designed to make the adult child feel so indebted that they capitulate.
Adult children can be equally guilty, bringing up childhood grievances repeatedly—not to heal them, but to win arguments or to justify behavior in the present.
What does weaponizing the past achieve? It keeps both people stuck. Progress becomes impossible when every disagreement pulls in a decade’s worth of unresolved history. The goal stops being resolution and becomes domination—who can land the most devastating blow using shared memories as weapons.
Can you think of a single instance where being reminded of a past grievance in the middle of an argument made you feel more willing to listen and change? Probably not.
The past absolutely deserves to be acknowledged and worked through, but there’s a difference between addressing history with the intention of healing it and using it as a weapon whenever it’s strategically useful.
Respect requires a willingness to deal with the past without treating it as a permanent arsenal.
7. Dismissing each other’s feelings as overreactions.
“You’re too sensitive.” “You’re being dramatic.” “Back in my day, we didn’t make such a fuss about things like this.” These phrases might feel like honesty or even a helpful perspective to the person saying them. To the person on the receiving end, they land as rejection.
Invalidating someone’s emotional experience, regardless of whether you understand it or agree with it, communicates that their inner world simply doesn’t matter to you. And that is a disrespectful message to send, even when it’s delivered without any intention to harm.
For adult children, having their pain dismissed by the very people who raised them carries a particular weight. When a parent waves away hurt with “I don’t know why you’re so sensitive about this,” it doesn’t just sting in the moment; it can reinforce the deep fear that their emotional experiences will never be taken seriously in this relationship. That leads to silence, distance, and eventually a very different kind of relationship than either party wanted.
Parents experience this, too. Having their concerns, fears, or feelings brushed off as outdated worrying or irrelevant opinions is equally hurtful. Adult children who roll their eyes at a parent’s emotions are doing precisely what they’d resent having done to them.
You don’t have to fully understand someone’s emotional experience to honor it. Making space for feelings you don’t entirely relate to is one of the most powerful ways to show respect. And you’re allowed to do that even when you find the reaction baffling.
8. Using guilt and emotional manipulation as tools.
Guilt-tripping is particularly corrosive precisely because it disguises itself as vulnerability. “I guess I’m just not important to you anymore” sounds like honesty. What it actually is, in most cases, is a form of control—a way of maneuvering someone into a particular behavior without having to ask for it directly.
Parents are often associated with this pattern, and understandably so. Phrases like “after everything I’ve sacrificed for you” or “I just worry about you so much”—when deployed strategically rather than expressed genuinely—make the adult child feel guilty enough to comply. The relationship starts to feel less like a connection and more like a debt.
That said, adult children aren’t exempt. Using a parent’s past mistakes as ongoing leverage—raising them at strategic moments to extract concessions or deflect accountability—is manipulation pure and simple.
What makes manipulation so damaging to respect is that it works, at least in the short term. The other person does what you wanted. But something shifts in how they see you. When someone realizes they’re being maneuvered rather than communicated with, they stop trusting the relationship, and trust, once eroded this way, is extraordinarily difficult to rebuild.
Honest communication, even when it’s uncomfortable, builds far more durable respect than any guilt-trip ever could.
9. Failing to respect each other’s boundaries.
Boundaries are arguably the most contentious topic in parent-adult child relationships, and also one of the most misunderstood on both sides.
Parents who drop by unannounced, ask invasive questions about finances or relationships, or override stated limits around topics like religion or parenting styles are sending a clear message: their comfort matters more than their child’s autonomy. Repeated boundary violations communicate that the adult child’s personhood—their right to define their own life—is simply not being respected.
Adult children aren’t always completely innocent in this area either. Boundaries that are extreme, unexplained, or shifted without warning can leave parents confused and hurt. A parent who doesn’t understand why they’ve suddenly been cut off from seeing grandchildren, with no conversation or explanation offered, isn’t being respected either.
The way boundaries are communicated and enforced matters enormously, and that’s completely normal to find challenging when emotions run high.
10. Comparing them unfavorably to others.
“Why can’t you be more like your sister?” stings in a way that straightforward criticism never quite does. Comparisons don’t just highlight a flaw; they establish a ranking. They tell someone they’ve been measured against another person and found lacking. That’s an enormously different experience from being challenged to improve.
Parents often make these comparisons without realizing how deeply they land. A passing comment about a friend’s son who calls every day, or a sibling who “has it all figured out,” may feel like light conversation to the parent. But to the adult child, it registers as contempt dressed up as concern.
And adult children do this, too, by holding parents up against friends’ more relaxed, supportive mothers and fathers, or against some cultural ideal of what a good parent looks like.
What makes comparisons so corrosive is that they almost never produce the change the person making them is hoping for. Feeling fundamentally inadequate is not a strong motivator. It just breeds resentment. People don’t rise to meet an unflattering comparison; they pull away from the person making it.
Respect and resentment cannot share the same space for long. Once someone feels chronically ranked against others and found wanting, the relationship shifts. Emotional distance follows, and rebuilding that trust is far harder than the original comment was easy to make.
11. Inconsistency between words and actions.
Promises that keep getting broken exert a particular toll on a relationship. “I’ll stop bringing it up,” and then it comes up again at the next family dinner. “I respect your decision,” delivered warmly, followed by weeks of subtle undermining.
Over time, this gap between what someone says and what they actually do becomes its own kind of problem, separate from whatever the original disagreement was about.
Both parents and adult children fall into this pattern. A parent might honestly believe they’ve accepted a child’s career choice, relationship, or lifestyle, right up until a comment slips out that reveals they haven’t.
An adult child might assure their parent that they’re fine, that they’ll call more often, that things are going well, while their behavior tells a completely different story.
Neither person is necessarily lying outright. Often, they mean what they say in the moment. The follow-through just never arrives.
The damage this causes makes the other person feel like they can’t take you at your word. That’s a different problem from disagreement or even conflict. Disagreements can be worked through. A track record of unreliable words is much harder to recover from, because every future reassurance gets filtered through past disappointments.
Trust is the structural foundation of mutual respect, and inconsistency between words and actions erodes it steadily. Once someone starts mentally noting the gap between what you say and what you do, they stop relying on your words entirely.
At that point, the relationship doesn’t just feel strained; it feels unsafe in a low-level, chronic way that’s exhausting for everyone involved.
Final Thoughts
Respect between parents and adult children isn’t a fixed state. It’s something that either gets built over time or dismantled by it. Every interaction is a small deposit or withdrawal. The cumulative balance of those moments determines whether the relationship feels like a source of strength or a source of dread.
No relationship reaches a stage of strain because one person is simply bad at caring. Most of the damage comes from people who love each other deeply but haven’t yet learned how to show that love in ways the other person can receive. That gap between intention and impact is where so much unnecessary hurt lives.
The relationships worth having require the courage to look honestly at your own patterns, not just the other person’s. Growth at any age is possible. Connection, even after years of distance, can be rebuilt.
The desire to do better is always a worthy place to start.
