I'm 5'7 and 155lbs (ish). Im a dress size 8 i believe. I play sports and try to be very healthy. My ideal body is curvy but toned. My bf, however, likes very curvy girls. In fact, when I was a bit overweight apparently he found me the most attractive because I had larger breasts and a tummy.

My body is the one on the right. I'm slimmer now.

The point is, I want him to find me attractive so part of me wants to gain weight, however, by doing that, i know i won't be happy with my body and will feel unattractive. Should i try to gain weight and be what he finds beautiful or continue to lose weight knowing that he finds it unattractive? He's very supportive of me and thinks my body is beautiful now but he wishes I could "gain a few pounds" which is what sparked this question.
