Babayada has some good advice.
1. Have a really good cry. It will take 3 weeks minimum to get over it.
1. List 10 things you don't like about your ex. Go to alpha level and visualize each item on the list, like some horror movie.
2. List 10 advantages of ending the relationship. With that description of her personality, it sounds like you're better off. Can jou imagine if you had married her and then she pulled that stunt off. You just saved yourself some alimony payments. 
You've learned a lesson here. Learn it well and don't repeat the same mistakes again.
3. Change your attractor patterns so that you do not attract that type of person again in your life.
4. Go to the gym and work out.
5. Go to http://www.emofree.com/ and learn and use the EFT technique for lessening your pain.
