I think you have the right attitude. As far as the cold distant thing goes, my wife does the same thing when she is about to do something she should not, like be with another man or out on the hunt for OM. I am not sure how to handle it or if I should just put up with it. I think in your sitch, it is out in the open and you do not need to confront her everytime she is going to be with him. I think the more easy going you are the more she will be okay being around you. Maybe OM will start getting pissed off. Be a better man that he is. Walking the miles with you brother.

Expose yourself to your deepest fear; after that, fear has no power, and the fear of freedom shrinks and vanishes. You are free.
