However, I still can't trust him and as such I did a bad thing, which was snooping through his stuff :( He bought a new mobile phone a couple of weeks ago, and I found the old one and checked his messages from November.
1) So apparently he was incapable of telling a girl he had been seeing before that he was in a relationship now. He didn't meet her, but he was saying he was tired, maybe next week, but never telling the truth. I don't like this, but this wasn't the worst.
2) He exchanged messages with another girl and talked about going for coffee and that he liked her company. I couldn't understand if he wanted to get involved with her or if he told her he had a girlfriend and these messages meant that he wanted to keep her as a friend and just go for coffee.
Now I'm feel uncomfortable and don't know what to do. If I confront, I'll have to admit that I snooped, which is something very wrong. I also thought about doing bad things like creating fake profiles with her picture (I found her on facebook) or going to her workplace and pretend I'm a client... or even leave a recorder at his place overnight... But I don't know if I want to go down this path.
Please give me ideas... preferably something smart that doesn't involve things like fake profiles, but things that won't make me tell him I looked at his old phone :(
