<human>: Summarize the given text in a few sentences.

She and I have know each other for about 5 years and we have been class mates for 7 years. I have always had a crush on her since we "dated" (nothing happened; we only texted) in 6th grade. It was a 3 week relationship and it ended under unknown (to me) circumstances. 

The next year I called her New Years eve and asked her out (I was horrible with girls at the time). She said no and for the next 2-3 months she ignored me, which was the typical response I got when I told a girl I liked her. We are still really good friends, but we don't hang out every week and we don't have long conversations over text. 

Last night I posted (I'm not sure if that's the right term to use for Tumbler) on her Tumbler page, "so ya i think you're beautiful and have a crush on you. but you probably don't feel the same towards me. oh well." She responded, "Go off anon! Maybe we could talk!" 

I'm 50/50 on telling her. On one side it could go extremely well, but on the flip side it can backfire. I am leaning towards telling her but..... ehhh...

Any advice would be greatly appreciated.
<bot>: I [17M] asked her [16F] anonymously on Tumbler I had a crush on her; she said, "Get off annon! Maybe we could talk!" What  should I do?
