I love him so much, here is a long paragraph but i need help on this xx?

Well my friends tell me i'm a little obsessed, and I do think thats half true, but I just cant get him out my head...At first, i never used to recognise him, and my friend used to tell me he used to watch me as i walked past him. but i never really noticed and though it was nothing. then i got his msn addy and he started talking to me and we got on so well! then sparks flew and i sort of fell for him. then a couple of weeks later he asked me if i wanted to go out with him and 2 of his mates and me and my mate. so i said yes. we went out, and never spoke a word, apart from the words 'can i have some of your drink please'. i think it was because he was shy, and im shy so it makes us ever more awkard because we talk to each other online. then we got on well, then he started to flirt in a nasty way.. i didnt mind because he told me he was joking, but then he said something that really offended me and i started having a go at him. he told me to f*ck off. so i said fine. the next day we textd each other appoligising. but since then, we havn't been that close. its gone down hill. but since then, iv been out with him and spoke to him online (not in real lifet though)? i mean the thing that makes me think i love him is because i read this saying that goes ''IF YOU LOVE SOMETHING LET IT GO, AND IF IT COMES BACK, ITS YOURS. IF NOT THEN IT WASNT MEANT TO BE'' the thing was, we came back to each other? i love him so much! but i dont think he feels the same way. hes always on my mind, i need someway of getting over him, OR doing something about it. i need to know whether he has ever liked me? even before we argued? and before all the awcuardness? please help people =( xx
