Your friends here at EF will always support you. It will be over soon, and life will get better. Just remember that.
All i am personally concerned about is your safety. Just don't ever underrate your safety. Take precautions, because this man is obviously psychotic.
You seem innocent and reserved. I suggest that if you feel threatened, then contact the police. We hear so many stories of men, hurting their ex-wifes/girlfriends.
We all empathize with your situation. A date is a good idea. You don't have to have sex, because it might make you feel better. Sometimes it wouldn't make you feel better but vice versa.
Just be as close with your good friends and family as you can be at this point. And don't hide anything. Keep talking to everyone about this, just like in this thread. Talking about it will make it easier for you.
I wish you the best of luck. Hopefully days like these will pass as well. Like some good mates here said, "If it wouldn't kill you, it would make your stronger". Make sure no one hurts you like this again!
You deserve our support. Cheers to you.
