My husband had just watched a bunch of "24" episodes he'd recorded. He came up from his man cave and announced that if anything ever happened to me, he would marry Jack Bauer!
I replied that if he could get Jack Bauer to marry him, he would not have to wait until something happened to me, I would gladly step aside.
So you see, sometimes spouses leave for reasons that have nothing to do with UC! I definitely plan on becoming a cat lady along with MeowMix if that were to happen.
