I've heard of stories like this. Guy stops going, eventually gets fat, then the woman leaves him.
It could also be a ploy because the man is so attractive and gets attention from other women.
Never listen to women.
There's babes everywhere outside the gym. Summer is around the corner, if you live in a halfway decent city sexy women are going to be out in droves.
I'll take the super convenience of a home. If I want to see babes I'll just step outside my door
