I'm going to refuse to live with my mother
Why are you going to refuse to live with your mother?
I really don't like the way her house looks and her choice of furniture.
I know that you don't like your mother's house and her furniture, but you should respect her choices. If she likes the way it looks, then you should accept that. If you live with her you could suggest some changes over time that the both of you would be happy with.
I don't like change, I don't even like my mother.
Well at the end of the day you don't have to live with someone that you don't want to. No one is forcing you to do it.
