Why is she acting so strangely around me?

I work and there’s this lovely Muslim lady at my work. I thought we were friends, because she used to be really overly affectionate, running her hand down my arm, complimenting me on my clothes and kissing my shoulder, referring to me as her friend and talking a lot. Sharing personal stuff only with me. When she started talking about exchanging numbers, I gave her mine and I’ve noticed since she never got in touch, that she’s been acting weird, distant and seeming to hide from me at work. I am baffled. Was there something wrong with offering her my friendship? I thought it was ok, because she brought it up. I’m not upset that she didn’t get in touch, just confused about the whole situation.

I have trouble picking up on social cues so I’m confused.
