My girlfriend is always telling me how much she loves me wants when she's done school in a year be with me and have our life together and all. BUT a couple months ago I found her with an other guy at her place, she had told me she were with 3 friends... It all started there. That night I found an email sent couple weeks before to her ex saying she wanted to go see him and sleep over!! I backed my bags and left.. I came back after she was crying and all she told me it was to test him for her ego whatever, he's apparently very down and she wants to help him as a friend. So she cries and tells me how much she loves me.

Then I became suspicious. And I would not trust her and I kept on finding lies about her seeing her ex or hiding where she is and all... I had a hard time making her tell me the truth and every time it's apparently meaningless lies and she says she will do anything to win my confidence back. But she keeps on hiding little lies (example: tells me not keeping touch with ex, then I see tons of calls on her phone bill) and many other examples. So right now I left her and she still says she did nothing wrong and that I've left because I have an other girl or whatever... by the way I was seeing her when she was with her ex and I had noticed how easy it was for her to do such things behind his back... but then again she says it's because she was not in love with him... So, although I spent months enduring this situation I always thought she was lying do you think it's possible that she is innocent? We went so many times over the confidence issue she tells me I'm always coming back to that instead of trusting her... but she always gives me the arguments to not have trust...

Its possible since she lied and cheated on him with you, that she could lie, and cheat on you with him. Or any other sucker for that matter.

Forget her. She isn't to be trusted.

True girlfriends don't test their egos with other guys. That's BS.

Split, never talk to her again. Let her test her ego with that.

You don't need that.

Yeah find you a real woman that is not love!
