Long back story but we need to separate, all family agree and can't stand him, therefore resulting in massive tension leading up to Christmas. Mum does not want him to go to hers for Christmas dinner. He has been in previous years and she has been polite for my sake and the kids' sake, but she does not want him there this year. Enough is enough. I don't want him there either, but I am 99% sure he'll assume he's coming with us and that he will think there is absolutely no reason why he shouldn't. There are lots of reasons, but he doesn't see them at all. Anyway, I feel like I can't win, I'm going to give someone / many people a crap day whatever I say or do, or don't say or do.
