Please help! Long story short. Does she like me?

Met a bartender because I go to her work for lunch.

Invite her over to mine the following morning for some free stuff.

She comes, I get her Facebook and her age (5 years older than me) also told her that I'm leaving the city for a few weeks.

Then I go her work the same day, she insisted she pay my lunch but I refused.

See her a few more times didn't seem as happy to see me as before.

Messaged her on Facebook doesn't reply or anything.

She showed interest. What should I do? I'm out of town and will be back in a few weeks. That's when I will get to see her again.

Wait till you see her again and start up a new conversation.

There could be very good reasons as to why she didn't reply on Facebook. Give her a chance to explain.
