If he's married with 4 kids then expose the affair and that will nip it in the bud. He's just working your wife for something on the side.
I may try and do this. As I mentioned before, I haven't told her I know, and OM lives far away. I can probably contact the OM's wife via facebook and try and tell her that way, but I don't know either of them at all. I'm a little nervous doing it, but I guess that comes with the territory.
After I contact the OM's W, I'll confront my W. I'm not sure how to approach it though, since I can't really set boundary's since she isn't trying to repair our R, and probably wouldn't care about any boundary's I set, so maybe I'll tell her I know, and just go from there.
Thanks all.
