For some context, I don't have BPD, a person in my life who I love very much does. We have a relationship that's difficult to describe but I'm the closest thing she's ever had to a real "partner", she's opened up to me about secrets that she's never shared before, she's told me I'm the first person who's ever made her feel even a little more than worthless, I could go on but I feel like that establishes at least how close we are with each other. 

When I first met her I didn't know anything about BPD, and after I learned more about it I realized that I became her FP very quickly after we first met, and I stayed that way until a few weeks ago. I started to feel like she'd been more distant with me so we talked about that and she confirmed it. Now, I know this is objectively a good thing, neither one of us has to deal with the stress of that level of obsession, I'm mostly just curious if that might come back in the future? Like I've always told her since we started "dating" I'm not going anywhere, and I do plan to be a part of her life (I have seen how bad the BPD can get for her, and it hasn't been easy at the worst of times but I'm still not giving up)

So yeah, main question is, should I be expecting her to come back around to considering me her FP again? Is there anything I should do about that? Thank you all so much for your time
