Eliot's life right now is a living hell. This girls picture will be everywhere, she'll disappear, and then a year from now, she'll pop up. and everytime he'll get a stare that could freeze water.
That marriage is over. He'd be better off to say, "I fucked up. Take what you want, and I'll disappear." It'll be much less unpleasant for him.
Any guy here that's married will tell you the same thing. No bailing this out unless they were swingers before.
