Ok; so my parents have been married for about 18 years. My family was always like a loving close family, but once my mom found out my dada was cheating, they fixed everything and my dad stayed because my mom begged.
A few months ago I started to think that my mom was now cheating because she would go out almost everyday she would look so pretty, even prettier then going to a party, then come all messed up. I once heard her blow kisses to a someone on the phone, and sweet talk to someone and she talks on the phone almost all the time, but idoubt it was my dad because their relationship isn't the greatest.
Recently ifound a picture of a guy between her belongings , idont know who the guy is but I scaned his picture to my computer just in case.
My dad is always working and he never has time for anyone not even himselve so he probably doesn't realize this, but I have I notice everything happening, now I don't know what to do, should I tell my dad what I have seen and heard? Or should I stay quiet, should I tell mom what I have seen and heard and let her explain? Or what should I do?

By the way I am 14 years old.
& who ever wants to reply mean things I suggest don't even bother posting it please

I am sorry this is going on, but it is best you just stay out of it.

I think you should stay out of this. You have no right to tell your dad or confront your mom.
This is something between the two of them and it will be handled between them.
I'm sorry you feel stuck in the middle.

Stay out of it. They're the adults you're the kid.

Don't get involved.

I agree that you should not get involved in trying to fix things, or raise concerns about one parent's behavior to the other parent. It's kind of difficult because their relationship with each other has such a huge impact on you, but at the same time their marriage is just between the two of them.

If you are struggling or worried or preoccupied with what you're seeing and noticing, I would say you should go to the parent you are worried about - if you're wondering what's going on with mom, you can ask mom. You don't have to pretend not to see things or notice things. What you can't do though is to try to spy on one parent for the other parent, or otherwise put yourself in the middle of their problems. They can help you deal with your feelings about what's been going on in the family but should not involve you in fixing the problems in the marriage because that's entirely an adult responsibility.

Take care.
