They haven't spoken to each other for 6 years.
I suspect I get the blame as far as they're concerned, but DH says he just feels life is easier without them (could be pretty toxic).
I spent a lot of years trying to smooth things over when it all went wrong, then one day MIL told me not to bother next time, so I didn't and we are where we are.
Yesterday MIL text DH to tell him FIL has cancer and goes in for op this week.
DH has just responded to say sorry to hear that and hope it goes well.
DH is determined that's the end of his involvement.
I'm just really concerned that if it doesn't go well it will hit DH harder than he thinks.
