Living with somebody with such mental health condition can be devastating. I share the house with my brother who I think is a borderline. For several reasons i have to stay here until I get my pension. Then we will have to sell the house (I anticipate it will be a pain). Last year I posted about some episodes with my brother. A couple of months ago I had to call 911 as he was threatening me.
But I think what you are experiencing is worse, I believe Zinco advice is a good one
