Soundtest is right, you need to drop this chick like a bad habit. Seriously. Everything you've said is just setting off alarms in my head that say this girl is extremely immature in her dealings with people, or insane, or both.

First off, if she's willing to cheat in a relationship AT ALL, even if it's with YOU while she's in another relationship, THEN SHE IS WILLING TO CHEAT. PERIOD. If she'll cheat with you, she'll cheat ON you, despite what she may say or believe now.

She sounds so wishy-washy about what she wants, one day she wants you back, the next day some random guy is like "Dur, you're purdy" and she's got a new boyfriend. That's not normal, dude. That's not the kind of person a good, lasting relationship happens with. Maybe you had two years like you say, but I say if you did, you were damn lucky to have lasted that long.

I've never been in love, but my understanding of it is that you're not supposed to constantly subject one another to fucked up psychological mind games, which is CLEARLY what's going on here.

If you go back to her, she'll be using you like a tool, dude. Probably not what you want to hear but I think you need to hear it.
