If I do receive the petition, is this likely another back in line move?
If she actually files and sends you a petition, the likelihood that it is a "get in line" move goes down.
Divorce threats and very common with pwBPD. They generally like to "force" the other person to file so the pwBPD can assume victim stance and the "non" is the persecutor.
That's my answer to your question.
My real advice is to "not worry about that".
If you act and speak so as to get her to not file... .or in hopes that shew won't file, you are going about this in your own dysfunctional way... .and contributing to relationship confusion and dysfunction.
You are only responsible for you. We can help you "say what you mean and mean what you say" in a healthy way. Your pwBPD will likely use a variety of tactics, perhaps even legal filings, to get get you back in line. If she succeeds and getting you to return to dysfunction,
your life will be far worse, than if you had never tried at all Spend your time thinking about you... .and how to send your message... .because ultimate that is what you control.
What are your thoughts on this? How do you feel after reading it?
