Back in 2019, SIL's husband asked for a divorce. It was totally unexpected as things had not been right for some time.
They sold their house and went their separate ways. He bought a new house and SIL moved in with MIL and FIL and her daughter in 2020.
2022 - they're still living with the in-laws. SIL has not got over this relationship breakdown as has been permanently depressed since.
MIL insists we stay with her when we go and visit (we live about 4 hours away) and will not hear of us staying in a hotel. The house is cramped and it is like walking on eggshells around SIL in fear of saying the wrong thing.
MIL and FIL are now feeling very down because she hasn't moved out and won't be moving out until Dec 23 at the earliest. Every weekend MIL says has been awful.
DH is getting very irritated by it all and thinks she needs to move out and stand on her own two feet -I think in part this is also because he feels the house is too cramped for us to go and visit and for in-laws to spend quality time with our DC
MIL came to stay with us for a few days because she needed a break, but SIL constantly on the phone.
I don't really want to get involved or say anything because I don't think it is my place, but DH wants to call SIL and tell her what he thinks and the impact her depression is having on their parents. He feels their lives have been put on hold. I feel this will make matters worse, but do agree that perhaps after 2.5 years of living there other accommodation could have been sought (property prices are a lot cheaper in this part of the country).
Should DH call or will this make the whole situation 10x worse? MIL is upset that we are not going up for Christmas, but due to space and last year we don't want to do it again this year. It was not a very happy Christmas.
