Thanks for all the responses, guys. I really appreciate it :]

I guess I'll just go ahead and put it out there...

I don't know why I snooped. Things had been going so well for us and I just assumed that nothing could be perfect.. I guess I thought it was all too good to be true. I guess it was.

I found out that for the past 6 months, he's been logging into his ex-girlfriend's e-mail account and reading all of her e-mails. They don't talk anymore (they've been chit-chatting through e-mail recently, but I told him it made me uncomfortable and he said he'd stop).
I asked him if he had been checking her e-mails, and he lied to my face about it. I then told him that I had snooped on his computer, and he then admitted it. He wasn't mad about the snooping (which surprised me)... he was so utterly ashamed and embarrassed by it all. I've always been 100% honest with him about everything I've done, whenever I have a problem with him I always bring it up... I'm very avid on communication. He knows I've been hurt in the past by people that I loved, and he has too.

It hurt me so bad when I found all of this out. It leads me to think that he still has some emotional attachment to her, even though we'd been in a relationship for 5 months at that point. Since this happened, everything has spun out of control. I've had a hard time trusting him since, and we're currently broken up (or on a break, whatever you wanna call it).

A little backstory... he and his ex were in a relationship for 5 years and broke up 6 weeks before he and I started dating (she was unfaithful to him as well). If I had known this before we started dating (we met on match.com), I would've suggested we wait a while so he could have more time to heal from his past relationship, because I knew he would still be hurting from it, and he was. But alas, we hit it off well, so we took things slow and hoped for the best.

Well I'm beginning to think that maybe he still has some unresolved issues with her. He says he's over her, but that he needs time to himself for a while. I understand the reasons for this... I wouldn't want to get out of a 5 year relationship and then immediately jump into a new one.

We still see each other and it seems to me almost like things are the same... there's just no title. We still hang out (albeit not as much as we used to), we're still sleeping together on occasion... everything's pretty much the same but there's less pressure, I suppose (which is actually kind of a good thing). It just sucks for me because I fell in love with him, I recently moved to this new city where I only know ONE other person besides him, and I've never been more lonely in my entire life. He seems to be taking all of this pretty well, and I'm a f*cking mess.

Gah that was a longer response than I intended... I love you guys and appreciate all your comments... I just feel so helpless because I don't have any control over this
