(FP=favorite person, a concept prevalent in BPD if I understand correctly)

Has anyone here had success finding professionals who specifically understand FPs in BPD or obsessive love disorder? I've been in therapy (mostly CBT) for two years, but I feel like my FP issues aren't getting better, and it doesn't help that I notice myself avoiding the issue because my current therapist downplays what it is. I've heard a lot about DBT and was wondering if that helped with anyone's FP issues too. 

Some background: I've had beyond obsessive crushes since I was a kid. We moved a lot, first gen immigrant household, abusive parents, I was always lonely. My first FP was a female bus driver in second grade. I'd fantasize about us having picnics and her being loving toward me, I'd spend the entire ride looking at her eyes in the rearview mirror. Second FP was a boy in fourth grade. Had one in middle school and one in high school, both of whom I stalked online and even called using an anonymous phone number. Had a super shitty "twin flame" in my early 20s that was the first I had a real-life connection with... it destroyed me. I gave all my power away and my destructive behaviors with him (which ended up in him threatening a restraining order) led me to seek therapy. Things have been getting better overall, but I know I transferred the "twin flame's" FP nature onto this new guy. I'm trying not to fall into FP behaviors, but already notice the fantasizing and feeling so happy when he responds and on edge when he doesn't. It's frankly ruining my life. Btw, I put "twin flame" in quotes because I don't think that's a thing anymore--it's healthier if I detach from all those concepts. 

It sucks because these specific people are ALWAYS on a pedestal, separate from the rest of my "social life". I go on dates sometimes and am working on healthy friendships and relationships at school and I have no issues there. I know how to act, but I also just don't get any "high" from the dudes I date, even when they're great people. My current and last FP, I feel, have both seen my soul and they've said these profound things that others may seen as love bombing and they just fit the archetype that activates my crazy FP mode. Like bam, obsessed. I can feel it happening lol. It's like a curse... just wanted some support, insight, or to hear other's experiences.
