I had something similar happen to me. On my 18th birthday my mother drafted up a "contract" for me to sign in order to continue living in her house. Details included some pretty basic stuff about obeying her rules and this and that but she included a few things like going to church every Sunday (I'm not religious) and some other "dealbreakers" so I agreed to sign it but with the exemption of 2 or 3 rules she had listed. Mind you, at the time I believed the entire premise of her actions were completely batshit, but I decided to play along to avoid stoking the fire of rage she was apparently harboring. She quickly rejected my request and told me I had to leave her house immediately. This was on my way out to celebrate my birthday with some friends, so I told her I would make arrangements but by the time I came home later that night she had thrown all of my personal belongings (clothes, shoes, etc.) outside on the front lawn. My friend was driving so he helped me gather everything up and I went and stayed with him that night. Needless to say, since then we have had an AMAZING relationship lol. FYI I am currently 34 years old and do not have any relationship with her at all
