Single and very happy about that. I've tried the whole dating thing, and it's more hassle than I'm willing to work through. Plus, being in a relationship makes me unhappy. It's better for me to be free and able to make my own decisions and live life the way I want to, spending my time doing anything I want however I want without having to ask for another person's opinion. Like, I can move eleven hours away from where I'm currently living because I want to, and I don't have to see how it will affect someone else.
Plus, like Sandshrew4, liking people in that way just isn't in my cyborg wiring, so feelings like that are artificial to me as well. But hey, we're happier that way.
