We live in a different country from our entire family. We do not have enough room

in our apartment for barely ourselves never mind guests so when family visit they organize their own accommodations. Except for my Mother In Law. She expects to stay in my sons room with my son. (Hard no from us) My son is 2 years old. She says piously that she doesn’t want to put us out and will sleep in the corner on the floor in his room 🙄. This time we spent money for a Airbnb for her because she irritates the living F out of me and I can’t have her in my space. Anyway, when she visits - my husband goes to work every day even on weekends and doesn’t come home until she leaves for her Airbnb (she irritates the living F out of him too.) She was a neglectful mother and they have a bad history so every time she visits he goes through some emotional turmoil but at the same time he struggles with the fact that she is still his mother and has some kind of duty to let her see her grandchild (who she is very good to). I try to be as understanding as I can but I can’t help feel like I’m being taken advantage of having to entertain his mom (who again is HIGHLY annoying, whiney, insulting (to me) and rude) for 2 -3 weeks. Am I expecting too much for him to be home at least on the evenings and weekends when she is here?
