This whole episode was disgusting (though I guess all these episodes are disgusting). On one hand, her husband was quite obese himself, so I feel no sympathy for him. On the other hand, how pathetic is it that his entire life revolves around him cleaning that disgusting monster's folds and the literal shit and piss that she just lets loose in the bed? And she's so fucking entitled, she expects him to be her full time caretaker,  cleaning her piss and shit and listening to her cry and whine...meanwhile what does he get out of it?  Jack shit.  So I can't really blame him for getting with other (presumably slightly less horrifying) women.
