my immediate thought when I saw the 1st line of your post, exotic, was can you go to a different gym? I know how much it bothers you every time you see him, I know it would do the same to me. Obviously he's not going to respect you enough to change gyms, and you try to avoid him but keep running into him. So switching gyms seems like the only way to really be sure you won't be seeing him and having these little emotional landmines go off each time you do. Is that possible?
