Could not agree more and from the tone of the comments I imagine this guy comes home and treats his wife a subservient berating her at every turn. If he has not already done so I imagine he will be soon sleeping around looking for another victim to jump to.

I suggest you seek counselling for you superficial traits and priorities. Also look into what part of the problem are you. Did you lose your hair 2 years in and it depressed her so much she gained 80 pounds or was it that you were 
insufferable. Then get joint counselling...it could be as a former female athlete she may have gay tendencies and the weight is a defense measure to keep an undesirable partner away.

Please do one descent thing and that is encourage her to get counselling and if it is depression get it treated before you walkout and file for divorce.
