When you say dating, are you saying, just you two on a date, or you two hanging out with a bunch of people? Have you kissed her yet? etc. Sorry if you posted about this already, but I haven't read it if you have.

If you have been seeing her one-on-one for a few weeks, then all you have to do is grab your sack and ask her what the deal is with you two. The hardest part is bringing it up, but after that, reactions tell you a lot on whether to continue the conversation or not.
