So I’ve been dating really fit men recently and had a lot of fun. My problem is that when I follow FDS and get the commitment my attraction to them dwindles after a month or so because they stop going to the gym to spend more time with me. While I appreciate that , I notice they let themselves go and their bodies change. I’m no fitness model but I do have abs and maintain my figure in a relationship well. One guy made me feel particularly bad because I was head over heels with them but in 5 months he had a literal beer belly, otherwise he was perfect, but I couldn’t bring myself to let him go but he didn’t seem to understand why he has to change.then I noticed a trend with a few more like that even before they offered to be exclusive. Any attempt of explaining how I feel makes them resent me. How to avoid this?
