Ignoring her was a pretty bad thing to do. I think you should just talk to her, and tell her what you wrote up there. Be completely honest. Tell her you do have feelings for her. If she feels the same for you, then you know you've got something. You'd just have to work on calling each other when you want to hang out like that. Arrange places to meet, things to do, almost that it's like going on little dates or something, regardless of whether you see it as one. Maybe grab a few friends (like, two or something, no major party or anything) and just hang out, no making out. See what happens. You only live once, right?

look simply ask your feeling about each other, if you don't you will find your self with a lost of a very good friend, if you do you might even have a better one but you will have the comport of knowing what the answer is
