Need advice

[black thirteenth]

So theres this girl I've been interested in for the last year now, there's 3 years age difference between us, however her brother is in my year at college and always moaned at me when I used to talk to her, we like the same kinda stuff music wise and are both into the same kinda things however before for no reason I got a message from her on facebook saying she didn't want to talk to me any more then she blocked me, I've seen her in school a couple of times this year already as our college is part of a school and when I walk past her I want to say hi and ask why she stopped talking to me but I can never bring myself to do it :/ and I don't know what to do as I really want to start talking to here again even if its just as mates as I know she used to like me however I don't know what happened
Any advice would be appreciated, thanks c:

So... your 15 and talked to some little 12 year old girl, and her brother angry about it? or shes 18?

Dude, cut your hair and find someone your own age..

You could always assume befriending her brother as a positive advantage. You can ask her brother or her friends for her number if you really want to ask her to meet you in person and sort things out. Other than that you could also write an apology. I am not saying you did something wrong, but sometimes admitting you're wrong to girls is the key to it. Write a card or a note and let her have it. Still, if you're uncertain or lack of confidence, ask her brother first but don't let things get too obvious or you'll spill the beans. You could ask him what does his sister thinks of someone younger than her. If nothing works, maybe shit is just too damn early. You are 15. She is 12. I don't really like where this is going.

No, I'm 17 and my birthday is in june and she's 15 in a like 4, I just hadn't been on here in 2 years and so it still says that as I havnt changed it -.- and her older brother is an annoying asshole to put it bluntly, so I don't want to talk to him :L

Well, my advice still stands..

If i were her brother and you dated her, i would kick the shit out of you..

Not saying this in a harsh way, but I was asking for advice on this, and you're being a twat, so please just shut the fuck up up and keep your crap to yourself

I think you would do best just to accept she does not want to be friends for whatever reason - just liking the same music and similar stuff maybe not enough.

Yeah I guess, I just wanted some helpful advice from someone who's impartial, thanks for the help
