My mother has no boundaries, she doesn't respect other peoples boundaries and she doesn't understand the concept of having boundaries. Setting boundaries is an insult to her. After I requested her not to snoop into my ex's life, because this is not our, not mine and not her business anymore, she called me a control freak. She said, that it's not my business to control, what she is doing on facebook. Yes, she's right. She can do whatever she wants. But it makes me feel sick. And I don't know how to explain to her, what she is doing to me.
Some people don't seem to understand boundaries. This is something I, too, have struggled to explain to my sister about NC with our uBPDm and uNPDf. In the letter I wrote to her only a couple weeks ago, I tried to make it all as clear as I could. I will share it with you, so you can decide if you want to adapt it for your own case, "I am no longer going to be communicating with [so and so] in any way. Not mail, email, phone, or face-to-face contact. I ask that you respect my decision concerning [so and so]. In other words, please do not allow [so and so] to contact me from your phone number/email address/mail with return address from you or have either of us visit and throw us together to duke it out." I didn't think about it at the time, but I wish I had also said something like 'as [so and so] are no longer part of my life, please do not try to get me involved in theirs. This means, please do not inform me of their life or try to engage me in an evaluation of their behavior. Any relationship between you and me will be *only* between you and me.' Perhaps you could try something like that? This is only my imperfect thoughts.
I went back to my mother's house because I had no other place to live.
Also, I am sorry if this is out of line, but do you have a car? If so, it is absolutely possible to live out of a car and it is not automatically a bad thing. The term 'vandweller' in conjunction with a search engine may be of assistance if you are interested in that direction.
