Unfortunately, I didn't just give him a peck on the cheeks. It was a more involved kiss (making out , as some would call it). It was a drunken moment and it happened. I'm not going to kid myself and say that I didnt' know it was a mistake when I did it. But I was having fun and was being completely selfish. I know what I did was wrong, but I'm afraid it's too late.
He called me and asked me if I'm freaking out about what happened, and although I said no, and told him that i know it didn't mean anything, i know that he knows I'm extremely uncomfortable with the situation. He want's to date me despite knowing that I just want to be friends.
I'm in a bind and I guess will just have to learn from my mistake.
Thanks, everybody, for your advice.
