Is it normal to feel something for someone who is absolutely cruel to you?

Grr idk how to explain this feeling!Because hes mean not to mention called me out in public making me cry at the end of the night,you would think i despise him&want nothing to do with him!It was like that in the beginning but as i got to know his playfulness,innocence,it reminded me of myself.So from there i always smiled around him while still being kinda mean to me but i was like oh whatever&you know why?Well i can read people&he was very insecure so he played that cocky tough guy.I even told him&he smiled&looked at me&said YUPP that was good.But because hes mean,i was afriad to try to be a friend&help him.But recently,it was our time to be real with eachother it was like a movie.We got drunk&hooked up(I believe drunken minds speak sober thoughts however you say it)He told me everything!When we were finally conscious enough,he told me how not to tell anybody about these things only his best friend knew&now me.I remember i was blabbing out how he was special to me,hes not as bad as he thinks,what i thought about him,it just all came out!Then pheww for a while after i thought i was having his baby but recently found out im not!Thank the lord.So hooking up w/him was not all drunk,because maybe i wanted to to satisfy that thing I had for him&it so did&now sparked a new meaning w/ us not just being mean to eachother.So now,Im left w/(i havent seen him since hooking up&its been like a month)moving on hello hes mean to me!Or,maybe the next time well see eachother(AWKWARD),itll be different&give it a chance cause idk maybe hell realize he needs me in his life&i can make him confident;-).Ughh,I just dont wanna look dumb wasting my time& him thinking what happened?We were drunk so who cares when really im sure he cares about what happened that night hes just in denial like usual.I just feel like something is calling me as my job to make him happy:)But to make someone who was mean to me happy?
