This is a delicate situation..but I'm here to tell you, fuck that. You just simply cannot let her treat you like a best friend, and dump you like that. She's using you now, and to that I say time to move on. She's truly not worth your time anymore if she won't even fess up either! I think she's a horrible person for that, if I were to ever break up with my girlfriend (as of 8 months), I couldn't just walk away and avoid her. As much as I'd like to, it makes an ass out of myself. Exactly what your ex did to you, and to that I say fuck her. Don't get walked upon, it's time to move on and find another fish. Even if she was "the one", she'd have to make out a damn long apology, and make up for her wrongs. Which I almost guarantee you 100 bucks, she will not. I'm sorry your relationship ended this way Alex, but all you can do is move along now.
