Either your current one, or if - to paraphrase from someone else here who posted a recent thread - you HAD one with whom you broke off a relationship.
I don't talk much about my S.O. for a number of reasons. Honestly, it's basically over now, but we met at a bar in the West Village 16 years ago. We were together 14 years - lots of ups and downs, but the best years of my life were good thanks to him. Though he'd probably say we never were significant others, just friends. Sigh. I guess that means I've lost about 60 IQ points since I was a youngster. Or was I just kidding myself all that time? Or who knows, maybe we WERE just friends, and I'm no good at love and a normal person would have been pursuing a relationship more explicitly about romance and love. (Of course, a gay person back then hardly was treated normally, so how could I pursue a 'normal' relationship with another man?)
Anyway, it was the proverbial love at first sight - full thick head of dark hair, slender build, sharp dresser, hypnotizing glance. He left and I chased him out, lol. But we talked, exchanged numbers and off we went.
So it's over now, and I need to move on, but I'm finding it difficult to let go of the anger and hurt. I will eventually, and survive, but I thought it would be therapeutic for some of us here going through this to share, or even if you haven't broken up with your S.O., just share your thoughts about him/her.
