I wouldnt care a wit about if she was overweight if I had the chemistry with her. That said the woman that Id click with would have drives and if she was unhappy with her body image I would support her as I would want her to be healthy and that means of ideal body weight. The personality is everything for me now, my days off trying to sleep with a different girl every night are over.
More important things than that, once it was all about the numbers, quantity and close to a ten when possible, lower ratings after drinking. Now I cant stand to be with a woman that I dont mesh with her personality regardless of how hot she looks, life's too short. Fortunately I mean alot of attractive females that have great personalities, but I dont try and sleep with them, that seems to make the friendships much stronger and life much easier.
Any overweight person with the good support and education and drive can lose all of their weight and look great, its very simple IMO and have seen many people do it.
Alot of women its an escape to eat and make her feel better, a vicious cycle, with support and caring that cycle can be broken in most cases.
