My first wife ballooned up to about 200 - no respect and I was embarressed to even go out in public with her.
A very common, though rarely stated, attitude by men. Women reflect on a man's worth. A beautiful woman is seen to be "worth more." This cuts right to the heart of the thing, so it's mostly avoided in polite conversation.
While most men will swear up and down that they will still love and find their wives attractive if they put on weight, the honesty of this comment holds true for very few men.
These are the same guys who have the whole "fancy car/self-worth" thing going, too.
