DPs still live in the house I grew up in. DM has mobility issues so garage was converted to a bedroom and ensuite wet room for her. It was done by cowboys, damp and inhabitable in my opinion. The whole house needs thousands spent on it to be up to modern standards.
I have a sister who I have no contact with, neither do my parents. I've cared for DM for 10 years, through daily cancer treatment while looking after 4 DC under 5 while DF worked and buried his head in the sand. My sister never bothers, no calls, cards, presents. DF retired 3 years ago, they have my DC regularly, adore them.
DM told me last week that, because myself and DSis don't speak, they've changed their will. The house will be sold on my DPs deaths and the money shared between their 6 grandchildren.
My AIBU is: I live in a council house my DM could not move into. We have no downstairs toilet, only a bath, and myself and DP sleep in the dining room.
Originally, my DPs were going to leave the house to myself and DSis. I would move in and care for DM, with my DC and I was going to buy her out, all good. Now, there's no way I could give up my house to care for DM and leave my family homeless. AIBU?
