I think you should still love him, otherwise you wouldn't ask so much of him! Since you love someone, you should tolerate him. He may have neglected his appearance because of his work. As his girlfriend, you have an obligation to remind him. I think a normal man will care about his appearance! As for your saying that he is ugly because he has gained weight, it all depends on personal preference. Some girls still like fatter boys because they look safer! What you have to do now is not to complain about his change here, but to try to change him. I think he will respect your opinion! He will change. I am a man, too. Nothing to the woman I like! Bless you!
