Hello, I'm a regular on here but have name changed for this. Not sure if I've posted in the right section or if anyone can even advise me on this impossible situation.
My mil moved in with DH and I about 3 months ago. I knew it wouldn't work and warned DH but had to go along with it for various reasons that I can't go into without identifying myself. She has money and has a house of her own which is currently rented out. No health issues and could live on her own.
Anyway, as expected it didn't take long for things to go wrong and her and DH just can't get along and I can't stand her. She's said some awful things whilst staying here. Now as well as me, DH wants her out too. They had a huge argument where he told her it's best if she leaves and that we will support her and look out for her even if she lives alone nearby.
The problem we have now is that she refuses to go saying it's our job to look after her and that she has every right to be here. I just don't understand why anyone would want to stay somewhere they are not wanted. What can we do about this mess?
