Just came out . Now I have a problem please help ?

I told my best friend of three and half years that I have feelings for her yesterday. I am 14 years and bi sexual . What didn't make sense is that she flirts with me all the time and she told me that she is bi sexual too. I am so upset that I have spent the whole day in my room crying . When I told her she used the line it's not you its me and btw you have great taste I found it to be really insensitive . What should I do ? Should I ignore her for a while or will that make matters worse ?
