Has anyone done this?
My marriage has been unhappy for years.
A couple of nights ago, things came to a head when OH banished me from the house and made me stay overnight in a very seedy hotel.
It was a terrifying experience. Our argument had been over one of our adult children who lives with us and who often treats me badly. OH never sticks up to me and his removal of me from the house was, in his words, "to diffuse the situation" 
I really don't want to sell the house and I don't want to move out. We live very separate lives anyway and I'm happy to be "flatmates".
He has refused to leave.
