Boyfriend's mother making our lives a living hell
I have been living with my boyfriend for over two years now, along with his mother. Several years back, after my boyfriend went through a rough divorce and was experiencing financial difficulties, his mother offered to move in with him and help him with rent, and that whenever he found someone new and wanted to start a life with them, that she would move on and live somewhere else. She has two different nervous system diseases and although she can't be on her feet all day long, she can make herself food and bathe/bathroom herself. She's resided in a few different nursing facilities in the past but refuses to return to one because she would have too many limitations on what she "likes to do". She takes huge advantage of my boyfriend and I on a regular basis and has regular outbursts and fits of rage that often include a lot of her swinging her walking cane.
Now, my boyfriend and I are expecting our first child, and it's becoming a bit terrifying being here by myself with her while he's at work during the day, but we have no idea how we can get her out. Her overwhelmingly selfish and disrespectful attitude towards everyone has pushed everyone else that she knows away, and the disability check that she receives every month is nowhere NEAR enough for her to go to a nursing home now that Medicaid dropped her.
It's to the point now where we both dread being at home and it's becoming seriously emotionally and mentally taxing- especially now that I'm pregnant. We need advice!
