Please point out to me where in my little suggested "speech" above I say ANYTHING about what your WIFE needs to do. I must have missed that. I was only advocating you standing up for what YOU need going forward, and whether or not you're going to waste your time with the charade that would be MCingin her current state of mind.
But if you trust your DB coach, you should go with what they tell you if you think it has been effective.
