Stupid shit that I just can't shake...

Arguments via message don't really have the same effect as arguments in person, or even over the phone.

Ever heard of "girls and guys can't just be friends"? With some people, that statement is true. I let a friendship become more than just platonic friends not too long ago, and now it's this awful cycle of arguments over the internet. We've known each other for a long time and he's had a thing for me for almost as long. I kind of had a thing for him, too, so we got, uh, intimate and I realized what a mistake it would be to actually be in a relationship with the guy. I don't really want to lose him as a friend, but he's convinced that we'd be perfect together (join the club of guys who think I'm their soulmate, buddy). He's got this ugly, distrustful side, so he doesn't believe me when I say that I'm still single (the moment I date someone other than him, he will refuse to have anything to do with me, or so he claims). Another problem is that he wants me to open up far more than I'm comfortable doing. I am a private person in the real world, and there's a lot of things in my personal life and in my past that I doubt I'll share with anyone. He says that gives him an excuse not to trust me because I obviously can't trust him. I wish I could just ignore him permanently, but I can't just ignore the fact that we've been friends for some time now. Instead, I suffer through argumentative messages being sent to me on a regular basis. One of these days, though, preserving the shared past won't be worth the price.
