You as last-resort caregiver? Not bloody likely! Tho I do know of a woman that happened to, a friend of a friend, her H went off and many (many) years later returned, ill, and they are back together, her caring for him . . ..
About salsa -- did I miss it, or have you tried it yet? It is not difficult to learn at all and quite fun! I gave a lesson to the family at Thanksgiving (on request)! It's one of my best dances and the one I generally start w/ as a warm-up at my lesson. In down times I know if I put on a salsa CD it will MAKE me get dancing to it and improve my mood (endorphins of course). Highly recommend it!

P.S. - One of my salsa CDs has a Scottish group playing one, pipes and everything but still salsa -- very cool!
