Women are always on the lookout for the prince with the golden apples. In the meantime, they may settle for a less fortunate fellow. May be to her, you were the prince with the silver apples. May be, now she has found the prince with the golden apples. Immature women want bad guys. They want guys that they can reform / change. Now it might seem to her that she has changed you all that she could, and is now looking for another one to reform. Speak to her. Ask her why she would do this? Make her give reasons. If she hesitates, she might be seeing somebody else (cheating on you), so you are better off without her. goto end; If you want her back, go to her, smelling like a cigarette, with a cigarette pack half visible from your pocket. If she asks, tell her that you've gone back to smoking. Also you can light in front of her so she knows you need more reforming, and she might come back. goto end; If you want revenge, tell her that you've found the true love of your life, and let her catch you going out with another woman prettier than her. Tell her that you are really happy, and that with her, you were always sad, but couldn't tell her, and that it is a real good thing that she left herself. end: Also try praying (even if you are not religious). It seems to work.
this is this.
