Very long story short, but MIL was very unpleasant to me whilst alive (she has recently died, and FIL died many years ago). We are very fortunate that MIL has left us her house, and DH wants to move in.
I really don't want to, I have nothing but upsetting memories there, especially of MIL being very threatening towards me, but DH is saying it's his family home and he doesn't want to sell it, he wants to live there and will not be swayed. He lived there from age 5-25, when he moved into our current home.
We'd 'gain' nothing by moving there, it's almost exactly the same as our current home (which is too small for us) and is less than 500 yards away from our house. Granted there is a downstairs toilet, but we'd lose a driveway and have to park on the (very busy) road.
AIBU to stand my ground a bit and ask that we buy a house together that is our family home, rather than moving into his mother's (we will have enough money to buy a much larger house, and still put money aside for our children)? I moved into his home before this (gave him some money to make it equal), and have never chosen my own home. I'd like us to find a family home together that is better suited to our needs rather than trying to shoehorn our family into a house which is no bigger, no better, than the one we have currently.
YABU - Let him live in his family home
YANBU - You deserve to find your own family's home
