I strongly suggest you confide in a close friend, one who is very objective or see a professional counselor to take care of yourself first. Talking with someone you can get yourself together, reassure yourself that you are fine and then look at your options. Right now it sounds that he is not contributing to the relationship in a positive way but having a very negative, destructive affect. As hard as this sound, it takes two people who want the relationship and are willing to work at it. Either he wants to work at it, in which case couseling is a great way or he does not, in which case see a layer to protect your own interest. I know this from experience. Its the cold hard facts. Also be very careful as in many cases this kind of behavior can lead to domestic abuse, which actually it sounds like perhaps it is already bordering on verbal and emotional abuse. There are some good resources on the intenet on domestic abuse. Be very careful and take care of yourself
