Okay, so I've been talking to this guy for awhile. Lemme point out the majority of my friends are guys. I just like them better - they're easier to get along with.
So this guy is kind of a jerk, but he's not really mean. He just like, teases and makes fun of me a lot. I was talking to him the other night, and I said something about talking to much and joked about him "probably want[ing] to duct tape my mouth and hands" (we were talking on line) and he said "you know, I might just have to take you up on that," and we went into a whole conversation about like, tying me up and he made it like, really sexual.
Then last night I was talking to him and I asked him what he wanted (I meant out of life) but he turned it into a discussion about what we wanted in relationships, and then he asked why I was so curious/interested, and I answered honestly first, saying it was "just something to talk about, and gets me into your head a little." and then said (obviously sarcastic) no, it's because I want you. And he thinks I seriously like him! I can't convince him otherwise, and I totally don't. I mean, I like him as a friend, but that's honestly it.
I don't want him to go around thinking I like him when I don't. So how do I fix this situation? I've tried talking to him about it and calmly explaining that I really, honestly don't like him like that and that I was totally kidding, and he said something like "You can lie to me but you can't lie to yourself."
Yeah, he's kinda arrogant. But like...what would you do?
It almost sounds to me like he likes me, but he specifically said he didn't.
So I ask you, what the heck?
