DSD is in her late teens and lives with us. Her Mum is incredibly problematic.
The expectation was that DSD would go to Country X with her Mum this year to spend Christmas with their extended family.
When I say "the expectation was" we intentionally didn't make plans to go to my home country (Country Y) to spend Christmas with my family, we decided to stay in the UK and host DH's family here. DH's parents live in the UK but are also from Country Y, DH has family there, we have a place there, so we could have hosted everyone there but we chose to stay here so that DSD was "hedged".
It's now looking like there will be no trip to Country X. DSD can probably cope with her Mum for an hour or two, but not much longer. She will, however, worry about her a lot if her Mum is home alone at Christmas.
So, do I say to her that she can invite her Mum here?
DFiL can definitely be relied on to be polite to her Mum.
DMiL can probably be relied upon (early stages of dementia).
DSiL will be stone cold. She witnessed the abuse of her brother first hand. In front of DSD it's always "your Mum?" but if DSD isn't within earshot she only refers to her as "that " where the expletives are interchangeable (from a woman who doesn't use expletives normally).
DH would cope fine (but be totally against the idea from the outset).
I am absolutely clear that I don't want this woman in my house, I don't want her anywhere near us, but I also don't want DSD spending Christmas day worrying about her Mum.
I guess I'm asking if I should offer - while desperately hoping (and expecting) DSD says no? Or should I just leave it? If she says "yes" I'll cope, everyone "on our side" will cope.
Has anyone any experience on this that they can share?
