The kept man, by Jami Attenberg

No, this isn't about a male mistress (mister?); Martin, a famous artist and the husband of Jarvis, is in a coma after a fall. Jarvis is keeping him alive. She meets three men in a laundromat, men whose wives support them, and falls into an unlikely friendship. I liked learning about the art world, and Jarvis was an interesting character, and the ending was satisfying, but it was like eating a peanut butter and jelly sandwich on white bread - not enough to chew on.
