She's flirting right?

There is this girl that is in my group at church. She’s a pretty girl that I used to see every week. However since my schedule at work changed I can’t make the church group but 6 or so times a month. She always says she is so sad and missed me. When she sees me I get multiple hugs, she gave me a card for my birthday and Christmas cards as well. She tells me she misses me. When I told her I can’t see her for a few more months she said "That's unacceptable" and she said mutual friends of ours would set up a dinner for us to be able to hang out.
I am 99.9% certain she is flirting with me and likes me, but I want to be sure. She hasn’t given me her phone number either. Is she flirting with me or just being nice?
