I agree with the other posters. Your BF is 100% abusing you and you need to cut ties with him completely and never go back. Most abusers are remorseful but still do it again. People like this rarely change, so don't fall for giving him another chance. If you had a sister and saw her being punched full force when she was sleeping ....what would you tell her? You could be perfect and there will always be a reason for him to blow up again. Cut off all communication and get a restraining order if necessary....you deserve a safe and respectful relationship
