Topic: jealous rage

My boyfriend and I started out as a one night stand. That night he made it perfectly clear that all he wanted was a "friend with benefits" so in order to make myself look cool, I told him all about my past and the crazy stuff I had done with other guys. Well, we ended up falling for each other and have now been dating for 8 months. I know it's not that long but we are head over heels for each other except now he knows my past and can't get over it. He gets so angry all the time over it, even when it isn't brought up and it is destroying our relationship. I want to be with him, but I can't deal with this strain on our relationship. He knows I regret everything, I tell him that every day. How do I make him calm down?
