I've been looking into the theory of FP and my past relationships have always been something similar. I almost depend on my partner for my happiness, when I talk and spend time with them I feel incredible but when it stops I feel low. I want to spend all my time with them, just doing absolutely anything because I'm so attached. I get jealous when they show attention to others. I always thought this was because of my anxious attachment style but I'm not sure

When the eventually relationships ended I was incredibly empty and depressed, my first relationship took me around 7 months to get over but we were together for just 2 months. I've never felt that low except after a break-up, my mental state is dependant on my FP

It's also worth noting my previous FPs have always been crushes or girlfriends. Never a friend, family member, or teacher, etc

I'm confident I don't have BPD and I'm not asking for a diagnosis, but I'm wondering if anyone shares a similar experience to me. Should it even be possible to experience this without BPD?
