Should I ignore her/move on?

RPGamr
Long story short:
I have a crush on a girl. I confessed it to her long back, said she was okay with it. Went to a dance date too, so I thought she might take things seriously. However it has been downhill since then, she almost never tries to initiate a conversation, nor hang out with me in particular.
From time to time, I still drop hints that I really like her. But she always seems too busy with her friends or has little to say when we get time together. I still haven't seen any strong indication from her side that she too likes me back. The feedback is making me more distanced from her. Today she even mocked my feelings for her on a post reply online (on FB), not in a crude negative way but like "aww... -_- "
Should I just stop trying to interact with her? Just long enough that she tries to initiate a good conversation?
Or should I just forget her and move on? (Would be really sad but then again, nothing positive happening for me right now...)
Ignore her and wait for her to initiate conversation
Forget her and move on

Forgot to add this, we have some common friends so would it be awkward for me to talk to our common friends after taking the step?
