Don't know where to begin with this one... Basically looking for any advice you can give that might help me here.
She is crazy, never forget that, it will make things a lot easier.
The thing with ex's, is that you must never forget the issues.
If she was a bitch, then everything else about her must be devalued accordingly, and stay that way. That probably doesn't make much sense. I'll try to give some context.
One of my previous girlfriends I had been dating for several months just one day broke up with me, I found out that she'd been cheating on me for most of our relationship.
Honestly, I've still not gotten over some of the stuff that she did to me, and it really does bother me that I do project some of her worse qualities on my current girlfriend. The best way to get over it is just look past it and hope that your current woman isn't like your last.
