Slim or curvy?

I weighed about 125 pounds when I first met my boyfriend - I was at the slimmest I'd ever been. That was 5 years ago. I have always had a tendency to put on weight but have always kept it in check so if I put on a bit I'd be careful for a month and it comes off quickly. The yoyoing however has had an effect on my skin especially on my . Now when I lose weight the skin on my s is loose and wrinkly and I HATE it! I love the rest of me when I'm smaller though and its easy to look good. When I gain weight I love my but hate my hips and thighs, its hard to feel that I look good and I worry that my boyfriend wont be as attracted to me. Right now I weigh 150 pounds and feel like my is mive but love my other curves. Should I keep fighting weight gain or be happy with a curvier but not too heavy me - even if finding jeans is hard?
