She worth it? What was my fault? Advice. Please?

I met a girl on minecraft, she gave her kik, so we started talking for months and I told her sercets and she told me, we also video skyped (she's not fake) and I started building feelings for this girl, and she never knew, I tried to hint her by complimenting her but she never got it, (she lives in US and I'm from UK) she said she'll be coming here soon. One day I sent a photo of my friend in his uniform and she said he was cute, I let it slide. She told me she had cancer, it wasn't a serious one but I worried my *** off, I really cared for her health. Then I decided to tell her that I like her. She said she liked my friend a lot. I got depressed but a few days later she said she's over him cos she didn't want me to be mad. This made be love her more! One day her brother had her phone and I texted him, he had an issue with me and her, he said I was too old for her (6 months difference), I said I don't wanna fight, he goes off deleting the chat and telling the girl that you want to fight! Which is actual BS! I'm a nice guy, I asked 5 of my friends what they would rate me as a gentleman, they we're 10 out of 10. Now the girl I like is siding her bro! I had no fault in this and she was mad at me, for what? I asked her, she said cos I wanted to fight her bro! I asked advice from a close friend and bless her, she did not tolerate this but she cudnt change anything! I apologize with all my heart, she read it but no reply, but the girl talked to my friend in the uniform.

This isn't what you want to hear, and you'll probably completely ignore it, block it or down rate it or whatever, but its the truth: this was almost definitely not going to work. Regardless of how close you think you were, you never truly know a person over the internet. You met her on minecraft! She lives in a different country and I'm assuming you're pretty young so you probably wouldn't be allowed to travel out there to see her on your own even if you could afford it (which I'm assuming you couldn't). I know I know she's planning on coming over etc. But it is literally 99% sure to fail. These things do not work out. What you are doing is projecting what you want in a partner on to a girl that you don't know, because subconsciously you know you won't be able meet her and see who she really is - its purely escapism. I don't mean to sound horrible or be the bearer of bad news, but you'd be better off meeting girls that are actually near you at school or something. It doesn't matter if she likes your friend, because it almost definitely won't workout between them either. You'd be a whole lot better giving up entirely, putting the whole thing behind you and focusing on your own, real life.

I think its one of those awkward situations where there's a lot of space (literally) between you and her and in techno land things can be taken in the wrong way, like sarcasm ect. Particually dealing with other english speakers (from experience ex-aussie boyfriend) i find things have different meanings. Not saying this is what has happened but it could be that the brother doesn't fully understand your relationship be it friends or more. He's obviously being protective over his sister somthing that is natural in a family. Maybe take the time to contact him but not in a "look mate what's your problem" sort of way. Send him a message saying somthing has obviously happened for him to dislike you and you simply would like an explanation! In the respect of her saying the guy is cute. Most girls say that. Doesn't always mean anything more than he is simply cute. If she didn't feel anything she wouldn't have continued to talk to you after you shared your feelings. She may think it to be easier what with the distance, I think all in all some time to step back and breathe is good. Let her see what she is missing and if she really cares she'll contact you.
