Well, I've mostly been letting it go, I haven't persistently been pushing him for an answer. The biggest reason why I kept bringing it up anyway is that it's causing a strain on both us and him and his close friends and it's getting worse every day and therefore making me more insecure every day.

Just yesterday he had a major fight with "J". J had initially invited G along on a holiday with his wife and a handful of other friends, and upon realising that I was in the picture, asked me to come along as well. But G immediately got weirdly defensive and asked J why he was just assuming we were a couple. J, not realising he'd opened a can of worms, innocently went "well you two are clearly something so you can't really blame me for jumping to conclusions, just come along together" and G almost threw him out of the house, which in turn angered J and turned into a heated discussion/shouting match over who's the bigger idiot.

Just a hunch? I figured he's in his comfort zone where the status quo doesn't change. That's basically what he told me at first. "Why change something that works incredibly well?"
Except it's not working incredibly well, for neither of us. I think I would be alright with not putting a label on it, if I thought that's what he really wanted.

So, I drove by his house a few hours ago, just for a quick chat and coffee.
I wasn't planning on any "relationship talk", just missed his company.

He did something very unexpected. He went full-on Matrix on me. He told me to sit down and close my eyes as soon as I walked through the door. When he told me to look again, he was holding out his hands to me, a candy pill in each.

"After this, there is no turning back. Take the blue pill, and the story's over. You wake up in your own bed, free of any memories of our little affair, and keep believing what you want to believe without me complicating things. Take the red pill, and you stay in Wonderland with me, where I show you how deep the rabbit hole goes."

We all know how that story ended ...
