I'm not feeling too good about your W's request to go out for drinks on Xmas Eve after all that time she's blatantly ignored you. Alcohol, emotion, and holiday do not mix well when there's a M on the rocks (pardon the lousy pun).
My suggestion is for you to suggest to your W that you two volunteer at a local soup kitchen together. I wouldn't go for drinks with your W. My Spidey sense is telling me that your W is probably wanting to get drunk so she can BD you. I hope I'm wrong...very much so.
Or stay at home playing card or board games. If you're Catholic, maybe to Mass?
