If she and her boyfriend are serious then there's not really anything you can do about that, sorry. I've been there, I know what it's like and it's not at all nice. It's just one of those things you've gotta put up with to be honest. Think of it like this: if you know it's highly unlikely that you and her will "get together" then what's the next best thing? The answer being that you become one of her closest friends. I don't know what it is but after you fall for a girl with both of you knowing it won't go anywhere, when you move on the girl seems to be alot more helpful than other girls when it comes to when you're liking other girls and you need advice.
I know I'm taking the "give-up" approach but that's what I did and I moved on and found someone better (although that's a bit up in the air at the moment). By all means if you see an opportunity take it; I'm just giving my (hopefully) helpful opinion.
