The bit that boggles with me is paying his mother to watch over your DH after his procedure and sedation. I don’t know anyone anywhere who would expect money for watching their adult child when ill plus DGC.
Families do this as a matter of course.
Another aspect though, maybe don’t blame your MiL of your FiL is being domineering over this. One of my grandfathers wouldn’t let my grandmother help with GC because he wanted her attention and he said they had ‘done their bit’.
When he sadly passed, my grandmother helped where she wanted and got stuck in. it had been him stopping her.
Belfast another appalling attack, we need to ask what is driving this.

Just seen this on a sample menu for a hotel we are visiting soon


I am here to help my DS and ddil to bring up their children, not to make money out of them. You need to speak to MIL and explain to her that you can't afford it any more and she needs to brave up to FIL.
