My ex gf (6/10) got fat and ugly, I got jacked

My ex used to be pretty but she was insecure and overcooked any food she made. I dumped her after she hurt my feelings for correcting her cooking. Now she’s 170+ lbs, and I’m 225 lbs jacked. I don’t go out often bc I’m sociophobic but it’s cool to see my hard work pay off. She tried to get back with me but I said no and I really do feel better without her.
