What kind of club are you flying with, or is she just one of the more "special" members?
Does your club have an operations or safety officer? If not, is there another club officer that you feel comfortable speaking with? Are you the new guy and everyone is giving you the fuzzy eyeball at this point?

I'm still having trouble getting over the tattle-tale vibe from your post. Is she a CFI at least? Did you not call her back after a night of poor judgement? [insert coyote visual here]
