Been through a similar situation myself. She wasn't honest with you, and you were manipulated and used. No matter how wonderful the person you thought she was, well, WAS, you now know shoe she really is. You did the right thing for you by seperating yourself from this person, sticking with her would only excuse her desregarding you and your feelings. The whole, we're not bf'gf thing should have been a clue, but I know how that is. When you fall for someone, subtle hints that things are amiss tend to fly over your head. It's a bitch only being able to see stuff like that in hindsight, but that's how some of us are doomed to learn I suppose. In any case, I have no idea how to do forge ahead, but my own experience tells me that the best you can do from this point is to try and let thhis whole thing go over time so that it doesn't eat you up and make you bitter. There are users, and abusers, in the world. You've seen that first hand. Yet, though I generally loathe the context with which this line is used, there are other fish in the sea. It would be a lot different if you simply viewed the girl as a good friend as benefits, but some of us have a hard time viewing things as such, esecially when they feel wronged by the third party. As you can tell, I'm a bit confused by my own version of this, so take the adivce with a fistfull of salt. Best of luck.
