You can take time to think before deciding. You can decide to protect your feelings by interacting with her by phone, email, or a neutral place, to discuss Christmas plans. You can just listen at that time and say, i'd like to give that some thought, so you dont feel pressure to decide or argue at that time. Positive interactions are good. My h was not in an affair, he just wanted out, and we did a few christmas celebrations pretending nothing had changed. It seemed necessary to me at first, then it felt more authentic and honoring my feelings to abstain from the pretending. Now i am detached enough to be around him at holidays, so the kids see him, but everyone knows we are separated and i dont interact with him much. So i can relate to every option of handling christmas. The first one is just hard no matter what. Put your child's interest first if possible.
