Is it normal to dream about him?

Hi everyone
Okay.. Im not rly used to ask for help, but since this happend to me, im rly desperate to get some help. So here is my story
Once for not long ago ( in may) i was to my uncles wedding in germany ( i live in Denmark myself) .. And there i met a guy, ( just to tell you, i am yezidian, my religion is ezidi, and its not normal if a guy and a girl talk together, they have to do it in secrets) so this guy found me, had a huuuuge crush on me, (he was the brides brother, and my other uncle had merried his cousin,) so his cousin/my other uncles wife knew about it, becuase he had told her to tell me that he liked me and wanted my number.. So poor guy waited for 3 days before i responded.. And he was rly going mad for not talking with me.. So i went home to denmark and saw that he had found me on facebook... So we talked alittle and he asked for my number...  i gave him my number and we talked.. At first it was rly sweet and fun, but after some days he stopped call much, he only called at nights ( and everyone were sleeping, i had bedroom next to my parents, and i was afriad they could hear us) and another thing: he only asked me random questions as " how are you" and it began to be rly boring, cus i rly wanted to know him better,so i told him to call me in the morning... 5days passed, and he didnt even call once ( i couldnt call myself, cus i was afriad someone else would pick hos phone) but i called, he didnt take his phone, but wrote a message saying: hey i will call u tonight.. So i was like okay then... In the afternoon he didnt call... So i wrote him back asking if i should call? He was like naah, im by my cousin ( another guy cousin), so i got mad at him and said " ur by your cousin but u couldnt even give me one call in 5days?" he was like :i was in hospital for 5days" i asked " why havent u told me so? Ur sister ( the bride) and his cousin ( my other uncles wife)  would have told me if so.. I got rly pissed off and he was like " ill call u tomorrow" so next day he calls 5 times before i pick up.. So i start yell at him etc.. And he couldnt say a word he only said " ok.. If u want, i will delete ur number, and never talk to u" i was like " oooo after all this then ur gonna leave me?? " he was like "yea.." and then i got quiet and he hang off.. So since that i been crying all the time.. And the most annoying thing is.. I see him in my dreams everytime.. In some he is rly nice to me, in others he is rly evil... And i dont know what to do.. I try so much to forget him, and i tell myself i am not in love, but i cant help it.. Everytime i try forget him, i find myself laying in bed, thinking of him.. Its been like this for 3-4 weeks .. Pls guys is it normal to be like this? ( he is kinda my first crush, and i am 19 yo, he is 18) pls help !!
