Should I break up with him?

I agree, i think that if you get home before him prepare a healthy meal, start with things he likes first and gradually move on to healthier things so it isnt just a big jump for him from kfc to a salad if u get what i mean. also i understand that you are becoming unattracted to him but if your love is true and pure then his looks shouldnt matter, however, there is a certain point to where you must feel an attraction to keep that love alive, which you sound like your not feeling, you dont want to come out and tell him that you think of him that way as it will discourage him but drop hints i guess
