Most likely this statement gets a reaction and that is why the pwBPD keep using it.
The trick is to not react and understand the underlying emotion so you can validate it.
Would you mind explaining this FOrmflier?
What reaction do they get? That it hurts us? They want to hurt us then?
That we move away from them? That we don't trust them anymore? That we think they are monsters with no hearts?
What can be the emotion in need of validation under "I was forced into our r/s from the beginning"?
Well, yes, I guess PBDh feels cra^p because HIS chaos is the cause of our relationship to end, and he probably feels guilty, ashamed and can't face it.
But I can't possibly tell him that, can I?
