<human>: My bf was in great physical condition when we met. In 10 months he's  gained 50 pounds and lost the muscle he'd built. He stopped going to the gym, or getting exercise at all. And prior to his getting in that shape, he was what doctors would call obese for five years or so, so I worry he's heading there again. We even talked about that in the beginning, how much he never wanted to be like that again.

He's 6' and a big framed guy, and I'm only 5'3" with very small bone structure, and I weigh about 115-120. Now when his body meets mine, I feel like I'm being bulldozed. I'm smothered. It's getting difficult to have sex. And we had an incredible sex life til now, the best ever. Different positions don't help much and seeing him naked doesn't do what it used to. Knowing his doctor told him he needs to lose it for health isn't helping.

I love him very much, more than I've ever loved anyone. I don't think there is a better man out there, he is the best. And we have talked about the weight gain, and he knows how it's affecting us but he hasn't made any real effort to get healthy again. He has said he doesn't see me look at him like I used to, and he's right.  Yet I don't want this to be a thing that breaks us up. 

The advice I need is... is there a way to deal with just no longer being attracted to your siginicant other?

Can you give me the gist of the text in a nutshell?
<bot>: I'm no longer attracted to my bf because of his rapid weight gain, but I don't want to lose him over it. How do I work around it?
