QUESTION

I am living with my partner for almost 2 years. In the 1st year of us living together, I discovered quite a few things about him that scared me, so much so that I wanted out of my relationship, but I am a devorcee, and do not want to just up and leave whenever things aren't going as smoothy as I'd like. The things that went wrong is, he wants me all to himself. I mean that no outtings with my friends, atleast not by myself. And if he does come along he just does not shut up, he has a comment to make about everything I discuss with my girls. He's also extremely jelous and can be shovinistic at times. Ok that's his bad qualities. His good qualities: he loves me for me, I am heavily over weight and not that great too look at, he helps with the chores and other things around our place. On the other hand he is also overweight, and suffers from high blood, but refuses to do anything about it. I feel like we should be eating healthier or at least trying to, and also do some type of execise, but he keeps me down. I don't know if our relationship is worth holding on to. I forgot to mention that he threatened to break everything in my house if I should try and trow him out, becos he said he'll never leave me or allow someone else to have me.
He can be very charming and sincere, but i would also like to live my life.
Please help?
