How can I get closer to her?

I met a friend of a friend and fell in love with her. She's relatively shy and likes geeky things, like anime, cartoons, games, and YouTubers, but she's a year older than me and is always with her friends. Whenever I'm near her, I barely know what to talk about. So much so that a few times I accidentally flirted with her, saying her voice was cute, and then ran away. She even followed me, but she wasn't bothered at all and was very happy with the compliment. The tricky part is that I barely get to spend that much time with her, so I have more opportunities to talk to her virtually than in person.. But it's VERY, VERY difficult to talk to her online!! She barely responds properly, and whenever I call her to play a game, she can barely manage it. I wish I had more opportunities to talk to her in real life, like on a date or something, but we're not even that close... And I'm afraid of seeming like an intruder trying to find out more about her, because there's so much I love about her, but I don't think there's anything to love about me. Man, I hate how complicated all this is. HOW SHOULD I KNOW MORE ABOUT HER??Σ(´□｀;)
