If we have been large all our lives, we have certain feelings. A woman that has given birth sometimes gains weight and can't lose it. And as we get older, gaining a few pounds is harder to take off. And some have a glandular problem to cause us to be larger. Now your S/O has had an affar, maybe a one night stand, or it has gone on a little while. You find out, or he comes to you and admits it. How do you handle this?
