Need advice from a girl, preferably?

[Ash]

Well, the facebook posts indicate she was missing you and didn't want to lose the friendship either - you're important to her. But the lack of response is a little confusing.
But then again, she may have gotten a whole bunch of notifications at the one time and not seen that you commented/replied/whatever you did.
She may have seen it and wanted to think about it, then forgotten to reply.

I'd message her again.
Someone once said "if you love something, set it free" yada-yada. That's crap.
Fight for what you love. Or value. Fight for what matters. She obviously matters to you. Let her know that!
