Why am i constantly attracted to guys that hate me?

I don't get it. I've seen a pattern in my life, i am an attractive woman, i've never really felt like it but i am. I am constantly attracted to guys that hate me. Have no interest in me, snob me or think their superior to me. It's weird as perfectly normal stunning guys have wanted to date me, get to know me, but once again, the guy that is not hard work, worst work kinda has my attention. There was a point where i knew he absolutely loathed me, and i hated him twice as much. Then he did something. He started acting nice, and his version of semi nice was endearing, i started liking his smile, or the way he laughed, stupidly i continued to gawk at his eyes, till he felt so uncomfortable, he was back to hating me again. This was ages ago. I'm seriously trying to get over a deluded crush, my mind says he couldn't stand you. But my body says 'he didn't touch you like he couldn't stand you' and 'sometimes he didn't talk to you like he couldn't stand you', he was cruel, arrogant,smug...and i know this sounds dumb, but my female intuition went crazy around him. Instinct kept telling me this guy wants to get close so from him making dramatic shows of finding me unbearable to sit next too or thouroughly repulsive, i could never let my guard down or be just confortable. I'm an outgoing bubbly person but when everyone was there i initially would completely ignore him, it's what i'm like with guys i really like. Because he didn't know i think he resented that. Then one day a colleague cracked a joke to him, they said the worst thing you can do is ignore him, he hates that. when it was just me and him, it felt like he would sit too close or linger, or he touched me once in the small of my back and it felt 'nice', and he said things that made me want to respond. It's like he opened a whole can of emotional worms, meanwhile dramatically showing everyone else he couldn't stand me. He probably couldn't. This was almost six months ago, i'm not there anymore, and this idiot is on my mind. What the hell is this, it's so unfair, he's not thinking about me in anyway shape or form. Mostly to ridicule or criticise, which is what he did often. Six-8 months later he shouldn't be anywhere near my thoughts, he was such an ******** as well. And i've just met a guy who is so sweet, why am i attracted to difficult men? Why am i thinking about this jerk, is it boredom...what the hell is it?
