I would strongly suggest that your boyfriend seek medical help for his OCD problems. If you feel you are in danger you should remove yourself from the situation until your b/f can get help and is able to control his anger issues.
You have to take care of you and if that means you see your own physician for your anxiety then please do that. Keep posting here as you will find many members that are supportive and caring.
Hugs to you
I am right here.
I agree with Lyn, a bit more info re his meds etc may help us understand his thinking. I am wondering if perhaps he has more than OCD going on here. He really needs to see his physician and he must choose to go for his sake. Please remember you cannot change him or make him do anything. He has to want to get better.
I get the impression that you are a very sensitive and caring person, so when your around someone that is hurting, or feeling some strong emotions, you tend to become empathetic with them. If your boyfriend is being abusive You have every right to be afraid and you should let him know that you are afraid. I also feel you may need to go to counseling as well to discuss these problems.
I know you feel love for this man but please, never think love is an excuse for anyone to be abusive.
Keep us posted and know we care.
