I Am Single

There is a girl I have liked for a while, most of my resent past experiences are about her also, but I am reaching out again. I really need advice on how to handle this. She is one of my best friends and I was her first friend in high school. A little while ago I told her how I felt, and after that we didn't really talk for a while. But now we are talking more than ever and I can't help but feel that things have changed. At this point I am sure it is obvious how deep in the friend zone I am, but I feel there is hope, can someone people talk to me and help?
