Regarding the morality clause, I was told it's something that can be litigated. For me, I feel it is my responsibility to my S to blow the whistle on this and do what I can to protect my S. Enforcing it may be another story. Like NTX mentioned, the threat alone often times will curtail activity. If they were become more secretive about it, that still prevents the exposure to my S, and that's more important anyway.
I don't know if the fact my W got up and left abruptly was necessarily a bad thing. At least I know she heard me.
The fact that when she got up and left and just stayed there was a 180 for me. I didn't apologize to try to smooth it over nor did I get up and pursue her. I just let her leave and calmly got up and left after she was gone.
