He Won'T Touch Me Because I'M Fat

I gained some weight recently. I've been exercising and eating less.. It doesn't help. I looked into my family history. I'm doomed to be short and fat. I'm five feet tall. I already weigh 135 pounds. And I'm growing. Out. Not up. My boyfriend doesn't touch me anymore. He says it's because we argue. We don't argue more than usual. But by the time I hit 125... Nah, he doesn't touch me now. I'm doomed...
