<human>: He has only been going for the last four months or so, but he goes too much. It all started after we were mugged by three guys. They were just irrationally violent and they were hitting us both with baseball bats. I had a broken finger and lots of bruises, he was a lot worse. We said a lot of stupid things after it happened, but I remember the first night in the hospital, I was sort of in a half awake/half asleep  phase and I heard him say "what kind of man allows the woman he loves to get hurt?" Honestly (I may be wrong but) I think that's why he started going to the gym in the first place.

It was probably a week after it happened that he signed up for the gym. It's pretty expensive and stuff but that's what he wanted to do so I was supportive. He goes to the gym twice a day (morning and night), plus he's always drinking protein shakes and cooking random healthy food. So much chicken. I swear, we've literally got  a10kg box of chicken breasts in the freezer. I've told him that he's going too much and he just says that exercise is healthy. I'm not really sure what to do.
