Wow, that didn't take long. Anyway, I gave her a call and she says that she does not secretly want you back. She just figured maybe you were grown up enough that the two of you could be friends. Then she asked if I was busy tonight. So yeah, based on that, I think it is over. (Told her I was not busy, but my wife won't let me meet up with her. Bummer.)
Seriously though, who really knows what is going on in her head. She wants stuff that you don't want, you broke off, she calls, you don't answer, you get mad when she talks to other dudes, you somehow thought that there was some kind of rule that you cannot talk to someone after a breakup (seriously??)
Find someone new. This relationship is over. Actually, she should probably have ended it over three years ago when you weren't being honest and faithful. So just be happy you got the extra three years.
