Well too late to give you advice, but I can offer you congratulations from getting away from that relationship. I hope that girl can see sense too because some people are just users and they jump from one victim to the next...

Keep as far away from him as possible. It sounds like he only wants to control you now and you don't need that in your life. Go out and have lots of fun. You don't answer to anyone, and even if you were with someone you still shouldn't have to.

And if you want to stay single, I think you should. Where's the rush? Take things as they come, do what you feel comfortable doing.

Above all, take care. Enjoy your freedom.
