cbtdad, I think it may be a good idea to discuss boundaries in MC if you haven't, I think it would be good for your W to understand them and for you to know what her boundaries are regarding other men. I'm not saying that she did anything wrong, because it doesn't even sound like she knew what his intentions were (I know the likely intention) or had a chance to say no thanks I'm married if he said anything to persue. I'm just saying that I don't know if no communication with other gender at all is realistic, maybe in this sitch it is, I don't know it's just not how I've ever felt. It is tough to think about OM hitting on the W, but trust is what's required in those situations unless they stay in a bubble.
