She Kind Of Stood Me Up 2 Months Ago, Then Calls Out Of Nowhere. Should I Even Bother Calling Back?

She left a message on my phone a few days ago saying to call her back.
Two months ago we were supposed to meet (we met online, albeit not through a dating site, she’s 26 I’m 21) and I called her to ask where we would meet specifically and never heard back. She’s pretty hot, and sounds really nice, but her beliefs (anti-christian, practices a little wiccan/pagan beliefs) are kind of a put off to me.
Should I just let her go and not pursue any further?
I think I should make friends first (see my other questions)
