Gee whiz... I read all of these forums and I don't see people talking about gyms and diets.... except in the health forum... which I stay out of... LOL.
But if that's the excuse you want to use for leaving, that's your choice. But I personally wouldn't let something like that keep you away if you are enjoying the friendships you are making. There are a few on here that really get under my skin, but I am not going to let them chase me away because I enjoy reading the forums. You get out of this site what you put into it. Just ignore those who want to diet or go to the gym because there are more of us here who are happy with themselves just the way we are. I think you should stay. You seem to be a nice guy.
