Hello 2lovingabpd! Welcome to the family!
I'm so sorry for your situation. It can be frustrating/confusing/painful/you name it being in a relationship with a pwBPD. It can also be rewarding and wonderful -- like any relationship. And we all know that well.
It sounds like you're doing a lot of things right. Setting boundaries. Changing responses. Recognizing and working on your codependence. All excellent.

I hope you don't mind if I ask a couple of questions. Is he now or has he been in therapy (and is there a BPD diagnosis)? What are some of the approaches you've tried? Can you describe what happened last night in detail? Knowing details can help us get a better handle on the situation and maybe help you with a little trouble-shooting if you're interested.
Keep posting and, again, welcome!
