how do i tell her l Really Like her?

ok i met this girl on a bus, she kept touching my hair, then we were joking around for a little while. a=she is a freshmen and im a sophmore, we botth go to the same school. when she saw me at school she said hi and she looked really happy. the other time i saw her i said hi and gave her a hug, but she didnt seem as excited to see me.

anyways, as a just made my facebook, i sent her a friend request, but she didnt accept it,= until i saw her another day i called her name and we both quick hugged, again she didnt seem excited to see me. So i tell her that i added her on facebook and she said "ijm pretty sure added you". isaid "no you didnt" then she just left to where she needed to go.

when she finally added me i saw her older status that said, "this is for the guy i like but never talked to, if you ignore me i will ignore you, if you dont start the conversation we willl never talk". I was thinking she meant ME, because we never really had a conversation.

maybe she feels like im ignoring her because i see her during lunch and dont say hi to her. Thats because shes always with her friends and im shy.

So 2 Days before school is over she texts me out of nowhere saying "GOODNIGHT & SWEET DREAMS<3". so the next day i called her name at school and she barely even waved at me, like whatevers.

Now School is over and i Messeged her on Facebk saying "ima miss you <3, have a great summer" and she never replied!! i also texted 3 days later saying, "Why are you ignoring me, i wanted to be friends" and again she hasn't replied!!

HELP!!
