https://bpdfamily.com/deciding_guide/04.htmMuch of what she has done has nothing at all to do with you. Her emotions came pouring out in odd ways... .you happened to be in the way.
This doesn't mean she doesn't have feelings for you (positive or negative)... .but the vast majority of the stuff is about something else.
So, imagine the "intensity" of feelings and relationship stuff that you have experienced since she has been back in your life. What do you think your life would be like if you experienced that level of intensity your entire life?
If I understand your story (of your entire life)... .you have had some big things go on.
Going to a T doesn't mean there is something wrong with you. They are a neutral party whose job it is to help you sort out where you are and what your priorities are in life. Well... that's one of their jobs.
Another one of their jobs is to help you find you. If all of this emotional stuff that you have been through is not about you... .then it is reasonable to ask... ."Where do I fit?" "Where should I fit?" "What is next?"
I would encourage you to have a well rounded support system and find a T you can get to know and trust.
The goal of a family and friends support system is to keep you socially connected without talking all the time... .(or even talking much)... .about the pwBPD traits in your life.
Leave that talk to your therapist... .and us.
Looking forward to your next post?
What is the biggest question on your mind right now?
