I spent five years in a marriage from hell like that in my early twenties. My oldest son recalls hearing me getting bounced off the walls and being afraid to get out of bed. And the whole time, I thought it was MY fault.
It took time and distance, but I was able to GAL that didn't include him. I am even able to forgive him. We are on decent speaking terms. Feel bad for the 4 wives that followed me.
The very first thing you have to believe is that NONE OF IT IS YOUR FAULT. IT'S HIS PROBLEM. Look at this as an opportunity to escape, not a failing on your part.
Run. You can't stand for a marriage that includes abuse, and you shouldn't want to. Circle the wagons ( I've been watching too much Bonanza reruns) with your friends and the start making a life for yourself.
I know, easier said than done, but it can be done. I'm here because my marriage is in trouble, but we had twenty good years, in which I was treated with love and respect, never hit.
