Ladies, am I being weird?

Try to shift your attention to another girl. Even if someday she will give in to your advances, it's still not worth it getting involved with a co-worker. You don't really want to mix business with pleasure unless you're some badass player who's king of his domain. But that's highly unlikely.

She's right about not wanting to have something with a co-worker. Keep your distance. It's for the good of both of you.
