My FIL is not a very nice man, to put it mildly. He is a racist, a mysogynist and perhaps the most selfish person I have ever met. His wife, my DH's mum is lovely. She dotes on the children and would do anything to help. She is retired and has been a god send through a recent difficult pregnancy. FIL is DH's.step dad. They are not close.
For the past four months FIL has been signed off work with a heart condition. I have seen much, much less if MIL during this time. That's fine, he needs her. I get that. Except, they have two other grand children from his first wife. So, his real grand children. He seeds them loads. They look after them for whole weekends; they are having them for the whole summer. He has been here twice since he was signed off with. Also, whenever MIL is here he rings constantly to find out when.she's home. He is extremely controlling.
I am home alone this week and my youngest two have chicken pox. She said would help with tea, bath and bed tonight but has just cancelled because he needs her to take him to a foot app. An appointment that wasn't made when we made these plans yesterday. I can't prove it but I am sure he's doing it on purpose; making it difficult for her to come. It's not the first time it has happened. He is however perfectly capable of taking himself to his own hobbies etc.
So, do I just suck it up? I don't want confrontation but I feel like it's so unfair.
Some advice please.
