If your boyfriend always jokes about leaving you does that mean he wants to?

The answer to your question is proably yes he will. Don't get upset because when he does he is going to feel terrible.He will always try to get you back even if you have another boyfriend.I made that terrible mistake 4 years ago and i am still trying to get her back. He might just want to know how you feel about him or he might just want to make you upset enough to brake up with him.
