Bit of background I do not get on with my MIL. She's lucky to currently have the weekly visit she insists on having now. She heavily contributed to my PND (8 years ago) and anxiety (now). I have had to go to talking therapies to get my head straight after all the damage she has done in the past. Luckily after the birth of my second DC my DH started to see just how manipulative she could be and we kept her at arms length. I have been civil so my children could have a relationship with their Nanna (or nanny as she calls herself).
My problem now is that after her mother died last year she would like to move in with us "for a month or so" until she buys a place for herself. This has made me physically sick and the stress is killing me. I've told my DH that I would rather have him move out than her move in with us. He keeps saying it probably won't happen but I think shes going to come one week and just not leave.
AIBU to not want MIL to live with us? She's 58. Shes lived alone before
