Anybody here ever find that upon feeling contentedness or joy that their reaction is to associate that with the guilt, pain, and sorrow from their past relationship?
Yes this 100%
I don't often post here [but I read here - A LOT]. Smarter cookies than me may elaborate more on this for you, but I feel confident to say that the subtle point you describe has an established cause.
Due to the BPDs mirroring of your good qualities [during the idealization phase] what happens is you fall in love... . with yourself! Your own best qualities get mirrored back to you... . and you fall in love with those.
This relationship might have been the 1st time in years that you felt your own inner joy [albeit mirrored]?
Your still feeling
your own inner joy its just that you came to associate it with your exPWBPD.
But it was
YOUR JOY all along.
Reclaim it! Brake the link of association between what is
YOUR joy and the exPWBPD
Its just a chain - delink it
2010's tour de force posts explain things much better.
