Why is he ingnoring me

Okay, so this is really geting fustrated..I thought me and this guy was fine, I was at hes 4 weeks ago, because im mates with hes bro.. And I gave him a blow job. ( I always do I can helo my self) we’ve known eachother 4yrs+ and he knows I’ve fanceyd him for the 2 years.. Anyway.. Getin to the point I kinder pissed him of and wouldnt leave him alone when he wanted to sleep.. ( I just cant help my self I like him that much I didnt want to leave hes room :( ) . Yeah o he go tup and went down stairs and told hes brother to keep me down here.. So meh.. He went up stairs and I follwed him back up and went ‘I love you night’ and he was like yeah I know’ and then he went in to the toilet so I waited, and when he came out I was like, ‘ do you want me to leave you alone perm? He was like im just tired, so I was like ill leave you alne all to gether if its what you want, and he just went I dont know, im just tired,.’ so I walked of back downstairs.. And then the next day I was going home’ so like he does early in the morning like 7am he comes and wake us all up. Before he goes work, to be annoying.. And anyways.. He hasnt been on msn in two weeks (we useually talk on msn). Well he has (he bene using he old account what I’ve had on block but hes only been on like a min or 2 because I’ve got a checker and it tell when somebody been on).. But he hasnt been online on the account I have him on..about 2 weeks ago he went to me mothers day :s (early in the morning (but he wasnt online you see because the checker said so).. So I left him a offline message saying wot you on about mothers day was ages ago blab blab.. And then a week later I texted him on my other phone randomly going x:) and he was like who this? So I was like oh it kate thought you had my number bye bye xx and he didnt text back .. And than this week, I’ve just texted him asking if everythings okay. And he hasnt texted me back.. (because he hasnt been on msn.. And he not really spoken to me).. Why would he be ingnoring me like this? I dont know what to do. Because, im ment to be see-ing him in about 3 weeks time, for a birthday hug. And hes not speaking to me :( hes ingnoring me, and I dont know wot to do it so fustrating >;[
