I broke up with my ex because she has no discipline. She doesn't take care of herself, she gain a lot weight, her car, room life is a mess. I hit the gym 3 times a week (she tried to get me to quit ) I keep myself and room car clean (she tries to move in with me and mess up my room and car etc). she was just a shitty person, I broke up with her and I told her I just wanted to work on myself, but that wasn't good enough for her and she keeps asking what's the real reason. should I just tell her ?
