Cheating

We have been together for about 9 years! He was sleeping and I couldn't find my phone so I went to use his to call mine. He didn't used to lock his phone but it is now. To bad he picked a password I know (his birthday). He was messaging unknown numbers so I did some snooping and there were pictures and videos of him with at least 3 other girls.

I was so disgusted I literally threw up til there was nothing left in me. I'm still in shock crying into a towel on the bathroom floor so that I don't wake our son from his nap.

What am I going to do I want to throw his phone at his face to wake his ass up but I'm not a violent person. Should I just pack a bag for me and our boy and just leave and go file for a divorce tomorrow?

I'm so heart broken
