YANBU, I am sorry but your husband is a massive shit. You did not consult him on something which is, frankly, a no-brainier. Of course you should be with your dad, and mum. Of course your dd should be with her grandparents.
Your husband could (IMHO) be whereever he wants to be. I would say that you did not consult him because you did not answer for him. You answered for you and dd because this is a serious illness and not a vague possibility of someone else not being around for Christmas next year from his family.
Are you happy with this selfish man who is tied to his mum's apron strings? The way he is behaving in the face of your devastating news is not behaviour I would expect of my six year old son, let alone my husband.
You have already apologized for not consulting him (which I don't think you needed to do as he was not open to negotiation, and as I say you have decided for you and your daughter, not for him).
If he does not want to offer you any affection, I would say so be it. Maybe he will grow tired of this childish behaviour and ask you how your father is, and how he can help you in this terribly difficult time, or other stuff which a normal man would be expected to do under these circumstances!
Can I ask what your dd is worried about in terms of not having Christmas in her own home? It is quite normal for people to go to different places for Christmas day and it sounds like every Christmas you went to your parents and in-laws, is that right?
Anyway, rest assured, it is not you, it is definitely him in the wrong.
