Is she jealous of my friend?

I noticed something about my crush this last few weeks. She showed up with this other woman at a happy hour event after work (co-worker thing). Me and her buddy always joke around and I guess it looks like flirting, it kind of is, but we’re just friends. I was particularly funny that night, I guess, because they were both laughing a lot. Her buddy and I also comment a lot on Facebook. Well, since that night the woman that I like (my crush) has been doing exactly the same thing as this other girl. She’ll tease me now, comment on my Facebook, etc. She didn’t really do that before, or not nearly as much. So do you think she loves me?

BTW – Last week my crush asked me what time I get off work on Friday, which she never has before. She asked two times actually.
