<human>: So we're both 16 and classmates in the 10th grade. We know each other for two years now and have since become best friends. We have the same interests, same sense of humor and generally a lot of things in common. We use to talk on Skype for at least an hour a day, and our topics range very much. We're very open to one another and even talk about our life's problems. We also hang out, but never privately, like on a date, but with a group of close friends. At school, we also talk a lot and at rare occasions even play/tickle/hug etc. I've been giving it a lot of thought recently, and I ended up liking her. I'm not having a crush yet, but I think it will lead to it very soon. What should I do? Also, I'm a realist. I know that I'm still young, she won't be my one and only, and that even if it won't work out there are plenty fish in the sea, so please don't give me that kind of lecture.

Can you give me a shortened version of the text?
<bot>: I started to like a girl who I am best friends with. I'm not sure if or how to approach this.
