Why on EARTH would you pretend you don't know? You were in there for a good reason. This is her bad, not yours.

tell your dad!

This isn't snooping.

That's awful. But don't cover for your mom. Confront her and tell her that either she tells your dad or you will. This is too big to keep to yourself.

I was the first one in my family to find out my dad was cheating on my mom. I looked through his phone out of boredom and saw her picture on his phone with some expict messages... I think you should talk to your mother and tell her she needs to tell your father. Be respectful. but one thing i know. If you are not happy in a marrage don't pretend its ok because you make it worst for the others around you. If love is gone then don't drag out your life unhappy and hurting someone else

yea confront your mother. or things will be worse for you and your family ;(

omfg, tell ur dad!!! or ur mum that u know, or hurt the guy she's cheating with.

Wtf..go tell ur dad. Your dad needs to know. If any kid found that out, i would take the phone and give it to my dad and tell them. But then ur parents would most likely break up and then u can only live with one.

OP, confront your mom or tell your dad. my friend was looking for her soap and found her mom's vibrat0r, when looking for her little brother's movie she found a p0rn video, she's also found an open cond0m pack and a used cond0m.

This actually happened to my sister, although she wasn't looking for anything, she found the phone because it kept ringing. She showed my dad and my mum denied it calling her a liar. Unfortunately, they've separated and I barely see my family other than my mum but your dad does deserve to know. Hope you're OK, hun.
