My BP boyfriend "spins out" regularly. Normally, it seems to come out of nowhere... .At least that's how it feels to me. He claims that I trigger him
Hey idesell, Welcome! Sure, the dynamic you describe is quite typical for a BPD r/s. A BPD storm cloud can arise out of a clear blue sky, as you note. Because he is seeking a reaction from you, I can see how your silence might trigger a rage. Does he goad and taunt you when you remain silent? It so, that could be his way of manipulating you in order to cause you to engage with him. You might want to check out the Tools (above) for possible strategies to lessen the conflict. No, you are not alone in the BPD "soup"!
