I think it sounds like OW is starting to put pressure on him about D and spending much less time at your place. I think he probably told her "After the holidays" and that is why he is now bringing it up. This is both good and bad. Good in that OW is starting to show her true colors, become demanding and put her insecurities before him seeing his son. Bad in that he is obviously willing to do things to make her happy - still an emotional tie there. Obviously, this is ALL speculation on my part, but if I were to take a stab that is my take on it.
Newmama, I think you are doing awesome in how you are handling this. Unbelievably strong and so so so classy. Someday, he is really going to regret this - I just so hope it is sooner than later.
