In the past when she would reach out I would get sucked into the "I am unique. Twin flames. True love" idea.
'Always and forever' First, best, never, knight in shining armor... . Yes, it seems the dialogue is very similar in BPD relationships.
But even while married to me she was reaching out to exes.
We were never married, but engaged. There were at least two ex's she kept in her orbit. One seemed to be a decent guy and the other one was dangerous. It was the dangerous one she gave our home address to -likely he visited while I was out of town. There was, of course, another work friend who appeared to be 'on deck'. All in all quite a mess.
I hope mine can get some help -I have a lot of pity for her, even after all the heartache she caused me. However... .I doubt she will.
The experience has gotten me into the therapy I need -so that is a good thing.
