Toxic Behaviours That Make Your Adult Children Resent You

By the time your child becomes an adult, the dynamic between you changes—or at least, it’s supposed to.

However, if old patterns stick around—controlling, dismissive, or emotionally immature ones—it builds resentment fast. The tough part? Some parents don’t even realise they’re doing it. They think they’re being “helpful” or “just trying to stay close,” without seeing how their actions are landing. Here are some problematic behaviours that will inevitably push your adult children away, even if the intention behind them isn’t malicious.

1. Offering constant unsolicited advice

There’s a difference between being supportive and being a running commentary. When your adult child shares something with you, especially something vulnerable, and you jump in with a fix or opinion straight away, it doesn’t feel helpful. It feels like you don’t think they’re capable on their own.

Over time, it becomes draining. Instead of feeling like a safe place, you start to feel like a critic they need to brace for. Even if you mean well, constant advice can feel like control. Sometimes, they don’t want a solution. They want to be heard as an equal.

2. Guilt-tripping them for not calling or visiting

When you say things like “I guess I’m just not a priority anymore” or “Nice to know you remember you’ve got a mother,” it might feel like you’re expressing hurt. However, to your adult child, it sounds like manipulation. And it creates pressure—not connection.

Guilt doesn’t encourage closeness. It builds distance. If you want more time with them, the best way is to show warmth and interest in their life, not make them feel bad for having one. Resentment grows when every call feels like a performance review.

3. Making everything about your own feelings

When your child opens up about something hard and your first reaction is, “Well, that really hurts me” or “I did my best,” it cuts the conversation short. It turns their pain into your pain, and makes it all about you.

Emotional hijacking like this leaves your child feeling like there’s no room for their truth. They’ll stop coming to you, not because they don’t love you, but because it doesn’t feel emotionally safe. Empathy is about holding space, not making it about your own discomfort.

4. Refusing to apologise properly

“I’m sorry you feel that way” is not an apology. Neither is “I didn’t mean it like that.” Adult children need accountability, not explanations that dodge responsibility. Owning up to mistakes, even small ones, goes a long way in rebuilding trust.

If your child brings something up from the past, it means it still hurts. You don’t have to agree with every detail, but you do have to show that you’re willing to take ownership. Saying sorry doesn’t make you weak. It shows emotional maturity—and it matters more than you think.

5. Treating them like they’re still a teenager

If you’re still telling your 30-year-old how to dress, when to eat, or what job they should be doing, it’s no wonder they’re pulling away. Adult children want to be seen as, well, adults, and that starts with respect. Even if you think you “know better,” it’s not your job to run their life. Offering your opinion is one thing. Acting like you’re still the boss is another. They’ve spent years building their independence—don’t undo it with casual condescension.

6. Criticising their choices instead of being curious

From partners to parenting styles to career paths, your child will make decisions that don’t mirror your own, and that’s okay. However, when you lead with judgement, even subtle forms like raised eyebrows or loaded silences, it eats away at your relationship.

Asking curious questions instead—without an agenda—keeps the door open. Even if you don’t understand their choices, showing interest without disapproval makes them feel respected, not managed. Criticism shuts people down. Curiosity keeps them close.

7. Comparing them to siblings or other people’s kids

Even if you don’t say it outright, comparisons sting. Whether it’s “Your brother’s always been more organised” or “So-and-so’s daughter just bought a house,” it sends the message that your love is conditional—or at least, competitive. Your child wants to feel like they’re enough, just as they are. Highlighting their “shortcomings” in comparison to someone else doesn’t motivate them; it just makes them feel like they’ll never measure up. In the long run, that wears people down.

8. Acting like you’re entitled to every detail of their life

Once your child becomes an adult, they get to choose what they share with you, and what they don’t. Pushing for information, probing about their relationships, or taking offence when they set a boundary only drives them further away. Respecting their privacy is one of the clearest ways to show trust. When you treat their independence like a threat, they feel smothered. However, when you let them share at their own pace, you become someone they actually want to open up to.

9. Playing the victim in every disagreement

If every conflict ends with “I guess I’m just the worst parent, then,” your child will stop trying to have honest conversations. That kind of self-pity shuts down resolution. It turns feedback into an emotional booby trap.

Being able to hear hard things without collapsing into guilt or martyrdom is what makes communication possible. No one’s perfect. But if you weaponise your feelings to avoid discomfort, you’ll end up making your child feel like honesty isn’t worth the fallout.

10. Dismissing or mocking their boundaries

When your adult child says, “Please don’t comment on my weight,” or “I need space after work,” and you roll your eyes or ignore it, they register that. Boundaries aren’t about rejecting you. They’re about self-protection and trust. Every time you dismiss a boundary, even jokingly, you teach them that being close to you requires self-abandonment. And no matter how much they love you, they will protect their peace, even if it means pulling away completely.

11. Expecting them to manage your emotions

It’s easy to fall into the trap of leaning on your child emotionally, especially if you’re lonely, anxious, or going through something. The problem is that when you treat them like your therapist, it flips the parent-child dynamic in a way that builds quiet resentment.

They’ll feel responsible for keeping you okay, and that’s a heavy burden to carry. It’s not their job to emotionally regulate you. They need a parent, not a dependent. Support should go both ways, but it has to stay balanced and appropriate.

12. Belittling their struggles or identity

Whether it’s “You’re too sensitive” or “That’s just a phase,” any kind of minimising language tells your child their truth doesn’t matter. When it comes to identity—gender, sexuality, values—they’ll remember every time you brushed it off.

Belittling isn’t always loud. Sometimes it’s quiet, sarcastic, or disguised as “teasing.” Of course, it lands the same. Adult children don’t need you to agree with every part of who they are. They need you to honour it. That’s what makes them feel safe to stay connected.

13. Only reaching out when you want something

Do you only call when you need help moving house, tech support, or to vent about your week? Your child notices that. They might still show up, but they also start to feel like a resource rather than a relationship. Connection has to go both ways. If you want closeness, make time to ask about their life, their joys, and their challenges,not just your own needs. When your presence only equals a task or a complaint, it becomes something they want to avoid.

14. Holding grudges for how they’ve changed

People evolve. Values change. Beliefs change. If you’re still holding onto an old version of who your child used to be—or resenting them for growing beyond it—it creates emotional distance fast. Your adult child wants to be accepted for who they are now, not who they used to be at 15. Letting go of your expectations and meeting them in the present builds trust. Clinging to the past? That just keeps everyone stuck.

15. Making them feel like they’re never doing enough

Even subtle comments like “It would be nice to see you more” or “You used to call every Sunday” can build pressure if they’re constant. Your child likely already feels stretched between work, relationships, and life demands. Being made to feel like they’re falling short with you too just adds more weight.

Appreciate what they do give, instead of focusing on what they don’t. Gratitude fosters connection. Guilt creates distance. Over time, the difference in tone will shape whether they feel safe coming closer, or emotionally safer staying away.

16. Refusing to grow with them

Relationships evolve, or they get stuck. If you’re still operating from old dynamics, using outdated phrases, or refusing to engage with how the world (and your child) has changed, resentment grows. Adult children want parents who are willing to grow, not just cling to old patterns.

You don’t have to be perfect. But if you can show that you’re open, listening, and willing to change when needed, that creates space for connection. Your adult child doesn’t expect you to get it right all the time. They just need to see you trying, without defensiveness or denial.
