The second I met this guy, I sensed within an instant that we wouldn't get along. I don't know why, but it was the most tense, uncomfortable feeling and never in my life have I experienced it before. He's a very bullish, opinionated and aggressive guy, stubborn but often quite chatty and funny.
Maybe it's a personality clash. But I developed a crush on him,

Anyways, what really bothers me is his attitude towards me - standoffish, distant and half-hearted. He never makes an effort to speak to me, never looks at me unless there's a casual glance, if I need to squeeze past him he practically jumps out of the way so I don't touch him etc. very, very standoffish. Yet with EVERYONE else, he's perfectly nice. It really is just me. Whether I back off, or make an effort, he's always the same. Just the other night, I sat down with a girl-friend, him and his friends, and he was unbelievably rude. He ignored my jokes and conversation, talked over me with his friend as though to disregard me, yet still said goodbye when I was leaving.
, he doesn't help or open up, he'll just point me in the right direction and leave me to it. He used to push my buttons quite a bit, too, picking up on and digging at me regarding small workplace mistakes. It's like he was pushing my buttons - now, he just acts like I don't exist.

I'm crazy about this guy - these feelings are rare for me, and that's hard enough, but now it seems he's so bitter and distant towards me that it's even harder to keep liking him. It's quite unbearable. Anyone able to de-code his weird behaviour, please help!!
