Girls, why does a girl act hot and cold?

[Anonymous]

co worker asked for my number a few weeks ago and hasn't texted me. Since then has been acting hot and cold. Can a girl acting hot and cold be a bad sign? What is the best thing I do if she is keeps acting like this? Should I give her space or does she want me to talk to her?

Emotions can do weird things, hormones too. It's normal for mood swings and things like that to occur in women.

I didn't see it from that perspective. Generally, would a girl act hot and cold if she was interested? Or is this a indirect way of leading me on?
