Flyintheweb, and welcome to the family! I am truly sorry for what you are going through! After 30 years, it must be all you can do to hold yourself together. Give it time. Your first priority at this point is taking care of yourself. Many people on these boards who have lived with pwBPD for years find that even sleeping through the night, having a day without fear, or being able to spend time on themselves, makes a huge difference.
You can't love without trust. that's the bottom line. With a sane person, there might be a possibility of going through a process of restoring trust, perhaps through couple therapy. A pwBPD this is practically impossible. Unless he is prepared to go to therapy for himself, and spend years re-learning his behaviour, your relationship will continue as it has in the past.
A more fruitful approach is maybe to ask yourself what is it about you that kept you in it for so many years?
Here is some reading that might help you think through that:
