A "messed up situation", you say? Let's see if we can put it into terms he might understand.
Once upon a time there was a wife who was unable to satisfy her husband's demands (for a son) - so she allowed him to turn to another woman (note: just one, not several of them regularly every couple of months for, "I'm going to say, three or four years").
But later she felt unhappy with the arrangement and asked him to stop it by sending the other woman away.
However, he refused and threw a tantrum like a man-baby, claiming everything was her fault and she was reneging on a promise to let him sleep with whoever he wanted, that she had emotional problems, and that she was projecting her issues onto him - oh wait, sorry, that last bit wasn't Abraham, was it? It was some other bearded bloke. Whatever became of him, I wonder?
