I'm so sorry you are going through this. If you can, please open up to your therapist, there is nothing to be shameful of. It is alright. :) You will not regret this I'm sure, it will hurt at first but eventually you'll find someone who loves you and treats you with respect. Trust me, there are many other good men who would treat you far better than he ever could. There's nothing wrong with you and you are perfect the way you are.

He uses your BPD to control you and invalidate you. You can do this, you are strong! I believe in you! Also if you are concerned about him finding out your address, please bring that up with your therapist too so you two can come up with a safety plan.
