Hi Dargumin,
I've read your post history and from what I understand you've been split up for 8 months and NC for 3. Is that correct? How are you doing?
It sounds to me like you're going through the phase that I did of wanting to save her still after parting ways and being concerned about others who will be affected by her. My exBPDbf was violent towards the end of our r/s and I was worried about the safety of others he would get involved with after myself. I posted here and the advice, whilst not what I wanted to hear, was spot on.
Let it go. As long as you're still focusing on her, you are not moving forwards. She is a grown woman, as are the other adults who associate with her and they can all make up their own minds for themselves. Any attempt now to give input to others about your suspicions will not come across well and as well meaning as your intentions are, it could open up a whole heap of issues for you. For starters, any potential replacement will most likely quickly be told about how awful you are and would only suspect that you are jealous and want her back if you were to speak to them. It is highly unlikely you would be believed and could easily be made out to be the 'crazy stalker ex'. Secondly, you've already mentioned she has spoken of r/o's and you do not want to push your luck with how serious she is. Reaching out to others now would only play right into her version of things and could be damaging for you.
Dargumin, the vast majority of us here are caretaker types, I myself recognise that I clearly have codependent traits. This is one of the reasons why we are appealing to a pwBPD. It is also one of the reasons that letting go and lifting the FOG (fear, obligation, guilt) can be so hard for many members, myself included. The kindest thing to do for her is to let her go, to live and learn for herself. You cannot save her. Nobody can unless she is ready to acknowledge and accept for herself the destructive patterns in her life. Interventions and informing people of your suspicion could actually drive her in the opposite direction to that. Time now to allow yourself to detach and focus your time and energy on healing. Have you read the article
Surviving a breakup when your partner has BPD? I'd highly recommend it if not, and if so, it would be worthwhile recapping. It contains the 10 beliefs that keep us stuck, and I'd love to hear which of these you feel still apply to you?
Love and light x
