I like my bisexual friend?

[Snow]

So I've been friends with the girl for a while, let's call her Emma for story's sake, and we kinda drifted apart for a while and then she wasn't at school for a while. Over this time, everyone was saying she came out as bi on some social media site. She came back to school this year, and then a few days ago my other friend told me Emma was checking me out. I used to like her a little bit because im 75% gay myself, but now i'm kinda on the fence of what to do since i'm not out. We've started talking again and she's gotten like, super gorgeous and is really nice. How should i go on about this? I've actually never dated anyone so ;-; Any input would be much appreciated thanks everyone!
