The American Idol guy is engaged, not married and iirc, he got engaged after her accident, although I think he'd already bought the ring.
If something were to happen to me, I'm dumping my spouse. She danced professionally, teaches yoga and pilates, was a personal trainer, surfs, etc. Physical activity, and sharing that activity with someone she loves, is very important to her. I'm not letting her clean my ass, wipe my drool, and confine her to a life without dick. She'd be gone, for her own sake.
