Relationship

Tori

So I really don't know how to feel about things because I have caught my boyfriend with messages from other girls and pics on his phone from girls and his ex wife( they're still legally married). Recently I looked at his phone and seen a couple convos on snapchat from girls (could only see 1 convo the other was just snaps) and a boob pic of his ex wife. I wish I could find out what all he could be lying about. His search history he searched for chat line numbers. We just moved into our own apartment, and I can't afford the bills if we break up. And to make matters worse I just found out my first love lives in these same apartments and I'm just a mess. Don't know what to do or how to investgate because he will instantly deny anything and we've recently had 250 come up missing and him or someone else is responsible for it.... Just don't know what to do. I don't wanna move back in with my parents
