Have i ruined a friendship?

so i've just finished year 11 and my friend decided 2 have an end of year party but there was only 7 people there includin herself anyway so the boy i fancy was there but i knew he was gona be and i was hopin sumthin mite happen but it didn't :-( but i hate myself for wot i did and i cud blame it on the drink but i knew exactly wot i was doin. I kept grabbin him and huggin him but he didnt seem to mind but after a few mins he wud walk away and anytime i would go near him he would start walkin away. He then started dancin with the other girls that were there but thats nothin out of the ordinary for him as we've been to loads of parties at the same house and thats just what he does but i never used to fancy him then. He knows i like him and wen i was lyin down hw started to dance on top of me kind of like a lap dance lol and we danced together a few times. I cryed about 7 times that nite and i just couldnt stop all my mates were sayin hes not worth cryin over and i knew wot they were sayin was true but i couldnt stop the tears as much as i tried, i kept goin downstairs to do this as i didnt want him to see but he saw me cryin and i sed im sorry to him and he said its alrite i then asked for a hug and he gave me one and i said i hate you and he asked why and i proceeded to say cuz you're so good lookin (one of my many stupid mistakes that nite). When we started to settle down i started swearin at him and sayin he was an idiot and i said i was gona kill him purely as a joke and it was cuz i was upset and frustrated that he didnt feel the same way. I then jokingly went over there and hit his leg lightly pretending i was killin him but im not sure if its cuz he was annoyed at me (which i dont blame him for) but he grabbed me and started draggin me round the room he then started to twist my ankle until it was really hurtin and then he stood on me on his way back to where he's been lyin down. I said sorry to him and acted like it hadnt hurt but i started cryin silently into my pillow and my mate nxt 2 me cud just aboout hear me and started to rub my back to comfort me. I now duno where to put myself as i feel really bad for what i did and i'm worried about goin to any other party incase he avoids me as i don't blame him if he wanted to and we're not the closest of friends but we have a lot of laughs together. Also i don't know what he must think about me: whether he hates me, knows it could have been because of the drink or maybe he doesn't care. I suppose what i'm askin is what should i do because of what i did as i can't stop thinkin about him and how i wish i hadn't come on so strong as maybe sumthin cud have happened if i hadn't been so full on with him. sorry its so long but it was one long and regretable night. Thanks in advance.
