My partner and I are poly and we've met someone that fits us so well. Since we've only known them for a few days, I'm still nervous about asking more serious questions or telling them about the severe side of my BPD. I'm scared I'm going to fuck this up. I want to be honest with my partner and this person but I don't want to scare either of them off. It doesn't help that I feel like I'm dating way out of my range and hoping they don't find out.

I just want some advice or comfort. I don't want to fuck this up, guys
