When a parent has an affair, the impact doesn’t end with the couple. For many adult children, it creates years of confusion, grief, loyalty conflicts, and emotional exhaustion. They are left trying to navigate a family system changed by betrayal, while often being expected to stay quiet, stay neutral, and keep the peace.

For those who are new here, I started this blog in 2021 to explore scholarly research on how a parent’s infidelity affects children, especially as they grow into adulthood (Click here for a list of the articles I have reviewed.) Soon enough, I realized there was a huge need for support after a parent cheats.

Over the last five years, hundreds of teen and adult children have reached out to me seeking advice, validation, and a way to make sense of what happened. Finally, last year I decided to figure out a more comprehensive way to help. So I created a set of questions designed to find out what exactly hurt most about having a cheating parent, where they have sought help, what kind of solutions people dreamed of, including what kind of support they needed right now.

Thank you to the 50 brave souls from around the world who volunteered to answer these questions and share such personal parts of their story.

What Hurts the Most?

For many adult children, a parent’s affair doesn’t just hurt, it rewrites the family story. It can leave them feeling blindsided, and unsure who to trust. One parent may have betrayed the family, while the other may have helped keep the truth hidden. The result is often a deep sense of confusion, grief, and the feeling of having to carry everyone else’s pain while no one fully acknowledges their own.

✅ Feeling invisible, unseen, or not chosen. Sometimes this meant that the cheating parent chose the affair partner over the adult child. But most often this pain was about the cheating parent not being willing to acknowledge the hurt they caused, and continue to cause, the adult child. The cheating parent would choose their own fear of owning their behavior over their relationship with their adult child.

✅ Difficulty trusting family members, especially around honesty and sharing feelings. Often the betrayed parent was equally eager to sweep any conversation about the affair under the rug, leaving the adult child with nowhere to turn. I heard this a lot:

I feel like I can’t trust either of my parents. 

✅ Boundary issues, especially the struggle to protect their peace without guilt. Some of the quotes I heard most often were,

I feel guilty for needing space.

How do I set boundaries without blowing up my relationship with my family? 

✅ Feeling stuck in family patterns they don’t know how to change, This is a category where the quotes say it all:

I’m tired of being the one who has to be mature.

I don’t want to keep pretending everything is fine.

I want an apology, but I don’t think I’ll ever get one.

All of this can leave adult children feeling responsible for their parents’ emotions, and even their mental health, while also carrying chronic stress, anxiety, and emotional overwhelm.

What Do They Dream Of?

They don’t just want better communication. They want to feel safe enough to speak honestly, set boundaries without guilt, and stop silencing themselves just to keep family comfort intact.

Specifically:

✅ To belong in their family without shrinking, silencing, or betraying themselves

✅ To finally heal old wounds and stop carrying pain that was never theirs to hold

✅ To speak their truth and be met with acknowledgment instead of dismissal, defensiveness, or ridicule

✅ To set boundaries without being swallowed by fear, guilt, or the need to justify themselves

✅ To stay connected without losing themselves, overexplaining, or doing all the emotional work

✅ To feel calm in their own body when family topics come up, instead of bracing for conflict or walking on eggshells

What have they tried?

Many adult children have already tried therapy, self-help books, and podcasts about boundaries or family dysfunction. While many found those resources helpful to a point, they often stop short of addressing the specific pain of family betrayal.

What’s missing is not insight. It’s two things: first, a practical framework for communicating and setting boundaries in the middle of a family system shaped by secrets, denial, and unresolved hurt. Second, a roadmap for healing their heart when the closeness, accountability, or emotional safety they long for may never fully come from their family.

What kind of support do they need to get there?

They need support that feels safe, validating, and specific to the reality of family betrayal.

A community where they can speak honestly about their parent’s infidelity without fear of being judged, minimized, or told to “just move on.” A place where their grief, anger, guilt, and overwhelm are understood instead of explained away.

They also need practical help: boundary-setting scripts, examples for hard family conversations, and tools they can actually use in the moment, plus space to practice what to say before they say it.

And above all, they need support that is emotionally supportive but not emotionally draining. It has to be practical, flexible, and realistic enough to fit into their actual life.

What I learned from these interviews is that adult children of a parent’s affair are not just looking for advice, they are looking for relief. They want to stop feeling overwhelmed by emotions, stop carrying guilt for wanting boundaries, and stop wondering whether they are asking for too much. They want a structured approach to healing that helps them rebuild self-trust, communicate clearly, and create healthier family dynamics without abandoning themselves in the process.

This is why I created this blog and why I keep studying this topic. The pain adult children carry after a parent’s affair is real, layered, and too often overlooked.
