Search Results: myspace hurting relationship

OK, My girlfriend and I have been having a long-distance relationship for about a year. Everything was normal until about a month ago. I noticed she had become more distant, and her emails and calls became shorter and fewer. I knew something was wrong. She had MySpace & Facebook accounts that I knew about, but I was never able to access them, and frankly, it never occurred to me to try. I trusted her anyway and I didn't have her passwords.

Well, a voice inside me told me something was wrong. I had a friend who was on Facebook, so I asked him to help me find out about her. My friend (who she didn't know) asked to be included on her profile as her "friend", and after being added, started to write to her. He inquired about her status, and she replied "I'm free as a bird. " That's where it stands now. Of course, my friend is backing off now! Now that I know she will cheat, if she hasn't already with someone else, what do I do? Remember, it was someone else talking to her, not me. How do I let her know that I know about her cheating? Should I confront her directly online? Or should I just act like nothing is wrong, and confront her when I see her?

I'm even wondering if I did something to cause this to happen? I'm not mad, just very hurt now! I keep thinking that maybe she had a reason for doing it. I'm actually still in love with her! What do I do? What's the best way to handle this, and respond to it? Help!
