<human>: Basically gf and I tried to do long distance and had been dating for 1.5 years, but I broke it off due to a variety of reasons in January. One of those reasons (not the main) was the lack of sexual attraction. She was putting on weight and didn't feel the need to exercise. She said I should love her no matter her size. 

Fast forward to last month, we have chatted and started talking and I see her back in the city where both of us moved from and she has added another 15-20 pounds. I was seriously so mad. I still really love this girl and have feelings, but the attraction is basically gone. I tried to be nice about it and she did the usual workout for a week then quit that she did when we were dating. I wasn't rude, but I was very up front in saying that in a long distance relationship there has to be a desire for sex with that person, otherwise it's just a friendship.

I honestly don't know what to do. Like I said, I do love this girl. We've been through a lot together but if I can't look at you with sexual desire then i just don't know how a relationship could work. Especially a LD one.

<bot>: Began talking to ex-gf again, saw her, she put on more weight and isn't near a physically attractive. Completely killed my desire for her but still love her. Need advice!!
