Hi w9isgrate,
Labels have value in the sense that they bundle stuff, accentuate stuff and make us focus. Labels are also inherently unfair to anything they are applied. It's been spelled out once - damage done - and also - value earned. This is now water under the bridge. Move forward.
You are dealing with certain specific unhealthy behavior. That behavior is common for pwBPD but it is unhealthy in general and it is also human. You are dealing with specific limitations and needs of your partner which are also common with pwBPD but also common to a maybe less pronounced way in the general populace.
The counselor wont call anybody out on bad behaviour, his position is that the person who acted bag has to realize it, if he says it, its worthless. How do I try and show her BPD issue while not attacking her and posing it in the most constructive light possible.
The counselor sounds like not be willing to play the role of a referee at least not overtly. Which to a degree may be a good thing as it prevents triangulation of the two parties via him. There is a lot of truth in that telling a person who is angry won't change a thing and the person need to learn for themselves.
What do you want to get out for yourself in these settings?
