Friend PROBLEMS, Help?

There's this girl I really like back in elementary school, I am now a freshmen in High school and so is she. I haven't seen or talk to her in over 4-5 years because I moved far away. Just recently I found her Facebook just by typing her first name in (lucky right?) and we started talking. She sounds so uninterested, shes giving me simple answers. Not what I was hoping after I thought me and her actually had a good friendship (we did). But I effed up, BIG time. I asked my friend and he gave me a stupid advice though he did not intend too. My friend is a poet/rapper so the he wanted me to tell her "You remember me but you don't want too". Bad idea, I got so desperate and typed that... After hours of realizing that was the dumbest thing to say, I quickly said "Oh wow, my friend told me to tell you this, stupid advice, sorry" and later she responded ">____>". SO basically I messed up, I got help from a good friend of mine who happens to be a girl, she told me to ask her "So hows it going?". She did not respond and totally ignored my message. Now my female friend is telling me that I should give her some space... I should have just left it the way it was! I wish I can go back in time and just end it when it ended, not go on with my friends. DANG!!!!!!!! Help???
