NOT the answer you want I'm sure, but the idea we all have that we have to be thin to be loved is absurd. My husband met me overweight and is still with me 120 lbs later.
I will say though that yes sometimes being obese is a turn off. Physical attraction is a large part of romance, and how you carry yourself plays a large role too. I think my marriage will be better when I lose weight because I will be more confidant and comfortable in myself.
