The last few days I find myself thinking about the past and my BPD a lot. I wonder if they are happy, if they think of me, if they miss me. Is this normal?
It's normal to wonder if that's normal, but that may not be the most empowering question yes? If you were to ask, with a playful curiosity, what's this about? What can I learn from this? What lessons are still there for me? your brain may just come up with stuff you hadn't considered before, which may prove enriching, and could add value to your current relationship and your life in general.
Is it common for your mind to go back there after all this time?
I dunno, I think about all of my exes once in a while, and sometimes I'll remember something they said to me years earlier that didn't mean much at the time, but years later it clicked what they were talking about, value long after the fact, by women who were far ahead of me at the time, and I didn't know it. But there's a difference between our 'mind going back there' and ruminating, even obsessing, about an ex. I would consider that unresolved business, time to see what my mind is trying to tell me, time to get busy.
I do at times miss my exBPD. I don't miss the abuse or drama but I miss the person they were when we first met.
And if your ex was a borderline, he became exactly who you needed him to be, the ideal mate, in order to attach, and it worked. And does that person exist?
I wonder if they have changed and are now "normal" and maybe it was me who was the problem. I am not sure where the doubts come from but every now and then they sneak up.
You can be sure he changed, like a chameleon, to assimilate into his current relationship and environment, something someone without a self of their own has to do, although you mean did the BPD traits go away? And wondering if you were the problem, your brain will generate 100 reasons why you were, how about instead going "hmmm, what do these doubts have to teach me now?" with the playful state again? Asking 'how can I use this?' What if everything happens for a reason and it serves us?
