Can i say to another even co-worker of mine, "geez that was rude." not in angry way,?

I personally think it was ok, no reason for her to be offended.SHE told on you, why are you feeling bad about it. It's a good thing you got it off your chest, don't you bother about her. She should get over it, if she wants to work alongside with you. Just be on your guard, you can't trust her!
