The rest of the conversation did not go well. She got upset because the family Christmas was going to be incomplete but was equally not suggesting alternative solution to us staying with them. I may or may not have said " there isn't any point in being upset, whether we have a family Christmas again now depends on if you or (my) dog die first" this was not my finest hour.
Honestly @Bs0u416d I have read all your posts and many of the replies, but can you honestly cross your heart and say that what you have posted is Exactly the way it went down, because there is something in your later posts that suggests that what we are being told is not the entire truth?
Did she really phone you and say, as an opening for starters, I'm sorry but I don't want you coming at Christmas this year because of your dog? Or did she say first, that this year she would prefer that you came without your dog? Which you then refused to do because a) you don't want to put your dog in Kennels for a few days and b) you were upset and made the above horrible statement in retaliation, without talking about compromises? Because it sounds more realistic that it was something like I have suggested and it therefore then sparked off into a row?
I do genuinely understand why you are taken aback, if it hasn't been an apparent problem before, but to be honest it does sound like it's 6 of one and half a dozen of the other as far as you and your Mum are concerned, with both of you wanting your own way as far as the dogs are concerned - and since it is your Mum's house, then she is entitled to say that she doesn't want your dog there?
It doesn't really matter why she doesn't want your dog there, the fact is she doesn't. If you choose not to put the dog in kennels then that's your choice. I don't think your Mum is putting her dogs above her child ( you), so I think YABU in this instance. Sorry!
