hi everyone, this is my first post on Reddit ever so please bare with me if I do something wrong. I was diagnosed with BPD last December. I’ve always been kind of obsessive w crushes and relationships. Right now I’m dating someone (abt 6 months) and it’s going really well and they really are a good support system and I really like them. Recently we both went out to dinner with a friend while out of town that we used to both know in college. During the dinner, I felt this weird connection to this person, they flirted with me and it was exciting. I haven’t been able to stop thinking about it since. I have been checking their social media several times a day and wanting them to talk to me almost everyday. We’ve talked maybe 3 times since the encounter and each time was friendly (I have a hard time telling where the line crosses over into being flirty). I’ve been up front with my partner about this crush despite being in a monogamous relationship bc it felt wrong to not tell them and they’ve seemed pretty chill about it, if not happy to hear me be really excited over something. I don’t really even know what I want from the situation or from the mutual friend. They know we’re in a relationship they’re not gonna come on to me. I don’t know what I’d even do if they did. I want to be able to stop thinking about them, I barely even know them, but I really can’t get them out of my head. Has anyone ever had an experience like this? Why am I feeling so much for someone I don’t know when I literally have a loving partner by my side?
