 I just came to know that my dad cheated on my mom. They've been married for 24 years. Should I confront my dad or do I tell my mom? My 16-year-old brother took photos of the chats that my dad exchanged with this woman so much so that he went to a different city to sleep with her. I am really disgusted and don't want to talk to him anymore and I'm sorry that you're going through this. I think it's particularly difficult when your parents are involved but here's a couple of important things to think about. Most people know when their partner is cheating on them but they consciously try not to acknowledge it because once you acknowledge it you have to do something about it and that can be really scary. So the first thing is don't push them into places that they may not want to go. If you are going to confront someone it has to be the person who's doing the cheating. And finally and most importantly yes it is your decision whether you want to reveal this or not but then you cannot decide how the other person is going to react. You cannot get a judge if they don't want to end the relationship or start a fight or something. You have to let them make that decision according to what they think is more important in their lives.
