What causes a girl to act a little awkward around you?

We have gotten along so well at work and we would always talk. For some reason she is acting a little awkward around me. It's making me nervous to talk to her suddenly. I end up literally freezing cause I feel conversation gets awkward. Nothing bad has happened between us and there is no history other than we talk at work.
