In short, my brother and SIL intend to divorce but she wishes to continue being a SAHM. Their children are 19 (away at uni), 14 and 13.
They separated 4 years ago and were cohabiting until SIL started dating a new man. My brother has quite a well paid job and managed to buy a 4 bed flat in the nearby city. It needed a lot of work but is finished now. He WFH a fair bit so has the kids there when needed. He does at times have to travel overseas for work.
My brother has also recently started seeing someone new. So, brother and SIL have started to discuss selling their marital home (SIL is still living there with the children).
SIL has been a SAHM since the children were born and this had been the source of a lot of friction in the marriage as the children got older. My brother had no problem with SIL not being in paid work, but she is a big spender. I have been at their house many times when numerous boxes of stuff arrived from Amazon. My brother eventually set a budget that SIL was not delighted about. She also has some debt of her own, my brother has paid some of it off.
SIL went back to work 3.5 days a week when they separated. This job suits her perfectly and she can sometimes work from home. However, a few weeks ago she started talking about 'burn out' and has now resigned from the job. She has no intention of finding a new job but is saying that she wants to sell the house, that her share should be 70% because she has the children living with her, and needs to buy a 4 bed house in the town we live in (which is expensive). She wants a sum of money to put into a savings account and she wants her new mortgage to be paid by my brother.
They are amicable (at the moment). My brother told me last night that she is now asking him to go to financial mediation because she thinks he is hiding funds. He has told me that he isn't, and has 2 savings accounts and his pension - which she knows about.
AIBU to feel that I've never really heard anything like this? When my exH and I separated, I immediately upped my hours at work to full time and my children were also teens.
