To me it sounds like she has borderline personality disorder. She wants your undying devotion and love and when she doesn't get it, (or even imagines she is getting it) she goes into a crisis and makes a lot of issues to keep you close. Such as when you leave she calls you back for some reason. When she freaks out and doesn't get attention she goes into full hate mode and you are the worst person in the world.

It takes two people to make a marriage work. Not everything may be her fault, but she definitely has some issues she needs to work out. You have to find a way to maintain your respect and well being if you want to stay happy with her. She needs to find a way to get her emmotions under control. Good luck too you.
