Hi, I'm 14 years old and a year or two ago I caught my mother cheating on my dad with one of their friends. The guy doesn't even live in the city anymore but she's still with him. I had no idea what to do so I kept quiet and I distanced myself as much as I could from her. At the same time, a boy in my class found out (and told everyone else) as I was telling my then best friend who also left me... But yeah. My mom caught me having a nervous breakdown and I ended up telling her that I knew. She talked me into not saying anything and I accepted. I know it's been a year but I am still so conflicted over it. My parents don't fight too much or anything so I guess I was scared to ruin that. I told myself that it was for the best not only for my family but also because my dad doesn't have any family. But now I feel like I did it because it was the easy way out and it's turning out to be not so easy because every time I'm alone with him I feel so guilty and so pathetic and I have no idea what to do so I guess my question is should I tell him? Or should I just keep quiet?
