Where do I spend Christmas this year ?

My boyfriends family who I’ve been with 6 years has invited me to spend Christmas with them and I’ve only done this once in 6 years.

But my mum who I don’t really get along with always has a go at me for even considering it.

I know Christmas is about family but my boyfriends family is much nicer to me, spends more time with me and helps me out way more than my mum and siblings.

I don’t get on with my mum or sibilings and I’m barely at my mums house ( where I ‘live’ and pay rent) but in all honesty I spend majority of my time at my boyfriends house. Also my mum hasn’t spoke to me in over a month and has left me in £400 worth of debt so yeah we’re not exactly on good terms.

I don’t want my mum to have a go at me and I also don’t want to upset my boyfriends family so what do I do ?
