I would leave. If you can endure such abuse, you are strong enough to leave. Contact your local women in distress org. and they will help you with what plans you need to make. Since you have some money now, it's important to make a clean break away, so you aren't responsible for his bills once you leave. (Calling any credit card companies and such and telling them you are no longer responsible for his bills..nor debt.. put it in writing, too.) Stuff like that.

If you don't have credit in your own name, and need it to get a place to live on your own, open a credit card with a savings account as asset... and then charge and pay it completely each billing cycle. That builds good credit.

Again, contact a local organization that knows all about how to do this safely.. and be safe!
