Seeing how she would apparently starve to death if he didn't bring her food, I deem it unlikely. I haven't got a clue why he does, though. If they are divorced and with no children, why? If he wants to keep supporting her, they shouldn't have ended their marriage. The dude just keeps getting stranger and weirder. Well, maybe he does view her as an animal, so he feels responsible like a pet owner who has a need a to let go of his pet, but can't do so until he finds a new owner.
