I agree with your post that he should go home and be normal. Staying away in this situation is not a "Man-up", it is passive aggressive or a mind game.
No More Mr. Nice Guy would probably advocate he go home and be as naturally cheerful and normal as possible. Don't let her mood dictate his moods. Don't react, and don't modify what you do based on her possible mood. Don't be a mind reader. Be direct, and be your natural authentic self.
