If it wasn't for the anxiety and BPD I would marry her tomorrow. So I am very fond of her - and we are able to have open discussions, but I would like to keep my head screwed on and research as much as possible to understand better.
Welcome!
You are doing the right thing becoming aware and also please take your time. I worked with my exBPD partner for 7 years, I saw quirkinous (spelling?) but did not realize the extent of it. We dated for about 7 -8 months where things seemed ok... .we had some things come up but he talked his way out of it. Looking back now I see the red flags but he didn't unleash the beast until I sold everything, uprooted my son, got engaged to him and moved in with him. Within a month, he was raging and kicked me out for the first time because my hair appointment and shopping for my friends birthday party took all day which meant I didn't want to be with him. My boxes weren't even completely unpacked yet. It devastated me. The switch from getting engaged and thinking we were going to spend the rest of our lives together to being devalued and dismissed over something so minor. So please take your time. The closer you get emotional to them, the more dysfunction you will see. Right now you are still in the idealization phase so it's honeymoon period right now.
There is a chance that she understands her BPD due to the therapy... .everyone is different. Just be open to both options and set your boundaries now. If they are crossed, get out... .because it will only get worse.
Best wishes,
