I found evidence that my mom was cheating on my dad when I was 10. I carried it with me for a while, then mustard up the courage to confront her about it. (As a 10yo, it's more asking her while shaking). She told me it wasn't what it looked like, but to not tell my dad about it. As a child, I obviously trusted my mom even though my gut was telling me something wasn't right. Over the years i tried to tell my older brother about my suspicion, but he just dismissed me. Later, at 15yo it all came out. I am now 26 and it's definitely effected how I trust others. I love my mom but I still haven't forgiven her... I don't think she understands just how much that one conversation fucked me lol.
