Do you watch NCIS? Do you know how Mark Harmon's character is always popping Denozzo on the back of the head? Consider yourself whacked.
Having that conversation with your S just put him in the middle, which my D's tell me is a pretty crappy place to be. Don't discuss that you're not going to be there, JUST DON'T. So tell your son you are running to Wal-Mart and just leave.
Sorry for the 2 x 4, but your son is old enough to handle his own R with his Mom. Just be the adult there for him when he needs it.
Brooklyn is exactly right. Have the convo with W that S needs to be left out of the equation, and that you will have no part in that.
