I think it's time to have a serious heart-to-heart w/S15. You need to explain in "only enough" info that he needs to have, that you didn't want the break-up of your family, and that his Mom's involvement w/other men is breaking the marital covenant. (She's introduced him/talked about them, right? You didn't reveal any of this to him yourself, right?) You are partially to blame for her/your M unhappiness, but you are/were willing to put the effort forth to make it better.
And, no matter what happens between you two, you will never try to degrade his relationship w/her. You're uncomfortable that she's involving him (a teenage boy) in some very adult issues, and you'll only do what's the RIGHT thing to do for your family and he and his brother. You aren't trying to hurt your W, only get her to stop her actions, and, otherwise, just raise the boys well.
Or something to that affect.
The boy needs to know this is wrong, but w/out bashing his Mom.

The average woman would rather have beauty than brains, because the average man can see better than he can think.
