What's the best way to break up with someone because they're fat?

[S.T.A.G.E.]

you shouldn't.
I know you need to find your gf attractive, but it just feels wrong just giving up on her.
The thing you should do, try to make her aware, and start working out WITH her.

if you don't want to do this, then just break up like normal.

Physical attraction is one of the foundational parts of a relationship. If you dont have it, its a wonder how they are staying together.
