Yes, please call a DV hotline. I am a social worker, and your situation is very dangerous, and WILL NOT get better unless you leave. You can only focus on YOURSELF right now, no matter how much love you feel for him. I don't want to be mean or scary, but you certainly won't be able to love him if he kills you.
Thank you for coming, and thank you for sharing. Please continue to come and share, and please call 1-800-799-SAFE, 24/7. As seekingcalm said, you are so smart and brave, and you deserve so much more and better than what he is (or isn't) giving you.
