32 ain't old. Weight can be lost when you're not out of your mind nervous, and if you want to live a happy life (no reason you shouldn't), just tell him "babe, do it again and I'm gone...." and mean it. Will he come after you? Maybe, but if you don't want to be found, there's ways to do that.
Am I being a hard case, yeah. I've seen too many men (and I'm male) do numbers on women's heads. You don't have to take it, and if you lose the weight, you don't have to go on thinking that he's the only one around. 17? Hey, if he's not gonna grow up, you have to. And stop running yourself into the ground!
