I don't think you're going to get a whole lot of feedback, because for one you posted virtually the same thing months ago and got feedback from some people on it. For another thing, yes, you keep writing the same thing over and over again. Also, a lot of what you write about this person goes outside the bounds of mbti, and is highly specific in nature to the problems you are having, ie financials, so-called narcissism, etc etc. Mbti doesn't get that specific. What you're describing doesn't sound all that different from a divorce, honestly.
Finally, you write about how she's low-level, how you'd like to make her a better person, how maybe there's hope, how you think a peaceful solution could be reached, how you keep trying to bring her back into your life, how you care for her, you, you, you. How sadly it might become a legal situation... blah. Well, MAKE it a legal situation!! Who cares? If she doesn't want you in her life, she doesn't want you in her life. End of story. It seems very cut and dry to me. She's moved on, you're speculating and psycho-analyzing for months on end about why she's doing what she's doing, just cut her off and move on with your life. Why agonize over maybe somehow bringing her back to a peaceful solution when she's for all intents and purposes done with you and the relationship? And why are you so invested in her anymore anyway if she's so low-level and narcissitic in the first place? Why are you holding onto someone like that? Actually, don't answer that -that's merely food for thought. You haven't moved on / proceeded legally because somehow it's more important to you to hold onto the possibility of resolution, and your 'love' for her, while spinning her side in a wholly negative light.
Again, this is you - all of your needs/desires. It seems somewhat evident based on her responses that you aren't her best friend, that she wouldn't be happy working with you, that she doesn't want to communicate every day, and that she won't be happy even if you would be.I called to tell her I loved her, that she is my best friend, that it's okay, that I'd help her get the help she needs, that I'd be happy to work with her together on an every day communicating basis so that we both can be mutually happy, whatever that may be.
You can call it anything you want, you can personally theorize that she's gravely harming herself, but honestly... it's her life. Take what she's doing as Fact, and if it's harming you, then do something about it. Take legal action. Be done with it already.
