Why do I stay with him? Can he change?

[Kay]

This man is potentially dangerous. Start making plans to leave, instead of doing it impulsively. If you're not living together full-time, start taking things back to your place gradually. If you are living together, then take important documents and belongings to a trusted friend or family member. Pack up when he's at work and have a safe place to go. If you have your own place, get the locks changed before you move back and get a dead bolt lock.

Get involved with a domestic abuse/violence program. They offer counseling and legal advocacy to women, whether or not they need shelter housing. This man is exhibiting serious control issues and is abusing you verbally and emotionally and you are afraid to break it off. Give yourself the opportunity for a happier and healthier future.
