I approached H and he gave me a curt apology.
Here is my take.
BPD is an "intimate disorder". When they are around people they are really close to (emotionally)... ."it" can and will show itself.
If there is no intimacy... .it can appear as though they are a different person.
Frustrating isn't it?
Here is the key... .once you understand this about the disorder... .you need to realize that you have control over closeness and "farness" (if that is a word) in your relationship. Use that to your advantage. I do.
So yes... .I will go and have an intimate weekend with my wife... .I can usually get away with a couple days worth, and when she "does the BPD thing"... .I'm ready for it... .generally ignore it and move along.
It burns itself out quickly... .and then life returns somewhat to normal. "Normal" for me is trying to keep my wife in a situation where she is "pulling slightly" wanting me to be closer.
Listen... .I think you and he did about as good as can be expected. You approached... he apologized.
Move along.
