I have this ~CrUsH~ on a guy thats sweet and mean at the same time?

SoOoO theres this guy thats soo nice to me at times and like helps and everything BUT then at other times hes the biggest jerk tht u could ever meet. for example at the dance he asked if i wanted to dance and i say yes and hes like "psych" and then i called him once and i had the biggest stomach ache and headache ever and he just started talking and made me feel better and like told me to go to sleep and everything soo i rlly liked at tht point. and then one day he was being SOOO mean & it was over phone and i was like rlly mad and i told him that i liked him and tht since he was being mean i didnt like him anymore. but i rlly think i do still like him cuz after the whole akwardnessity he was being all twofaced again but alot nicer to me so i dont wat to do im super shy so i rlly cant tell him i like him again cuz then everything just spilled out like tht. awww HeLp Me!!!!!
