Your post touches on something deeply personal to me: the generational echo of infidelity and the deep, often silent impact it leaves on the kids.
As someone who experienced infidelity from the child's perspective, I want to validate what you are navigating right now and offer a view from the other side of that dynamic.
I grew up surrounded by infidelity. My mother was my father's affair partner, they married, and his continued cheating contributed heavily to her eventual suicide. My entire family tree was riddled with it, to the point that it shaped my own early relationships until I finally did the hard work in counseling to unpack all that trauma. My father was an unrepentant cheater, but outside of his marriage, he was an attentive, dutiful father to me. Even so, the truth of his actions fundamentally altered how I saw him as a parent.
Because he was deeply conflict-avoidant, we never had the hard conversations. A permanent, unspoken wall went up between us. I pulled away and kept my distance, while he just assumed I was moody or giving him space. Then Alzheimer's took his mind, and he passed away last week without us ever clearing the air. That wall remained standing until the day he died, and the chance for genuine closure is lost forever.
The fact that your 25-year-old opened this door is a gift, even if it is painful to face. When adult children discover the reality of an affair, they inevitably see their parent differently. The childhood lens shatters, and they are forced to re-evaluate their upbringing, their memories, and their own sense of security. As your son mentioned, he spent years carrying misplaced resentment toward his father. Acknowledging that confusion and validating his pain is vital to dismantling the anger before it calcifies.
The affair carries a real risk of putting a permanent wall between you and your kids if you do not actively adapt the relationship to meet them where they are now. They need the space to reconcile the loving mother they know with the person who broke the family foundation, without feeling pressured to pretend everything is fine. When kids feel that anger, a parent's instinct is often to retreat out of guilt or fear of conflict, but retreating is what lets that brick wall harden.
You mentioned becoming a more humble mom, and that humility will be your greatest asset. Adapting to this new reality means meeting them as adults, leaning into the discomfort, and answering the hard questions without defensiveness. Showing them that your relationship is strong enough to bear the weight of the truth is the only way to keep that wall from going up.
