That means no!!
i would keep an eye out, it may mean shes hiding something, or hiding you if she doesnt talk to you and/or express her feelings towards you openly. talk to her about it!
It probably means he doesn't check his Facebook. He probably will accept you on Facebook bc being fb friends means nothing to most people. You are definitely concerned about whether he likes you since you are here. Don't worry about being Facebook friends get to know him offline, if he likes you then it'll work out, just have faith.
It means she wants to get to know you better
Depending on the status, she may just be curious to know who it was about.
if she hasn't replied its because she doesnt know wot 2 say or she is 2 shy
She is just letting you down easy (probably).
He thinks your the right one but he doesnt actually know.
Shes mad, she just doesnt want you to know it
Yes.
Go with "no". Whatever else it means, it means you are not his first choice.
It means she probally likes you and doesnt know how to express herself by simply saying she likes you
