Why are you mad? If you were apt to flirt and go along with what she was doing, then it seems like you are suppressing your feelings after realizing what you had subconsciously done. Anyways, flirting with a girl is nothing to get mad about, depending on what you think about her, it should be flattering not enraging.
I'm furious because I made a commitment not to get into a relationship or allude to one so willingly at my age. Instead I reacted the only way I knew how because I didn't want to be firm and refuse since I finally made a friend. I'm not attracted to her in any way romantically. Whatever the case is she was just fired for making inappropriately sexual gestures at other counselors in the work place (made my job quite wearisome having a pursuer hound me whilst I was alleviating the symptoms of sick children today) but that isn't really germane. To explain in a synoptic manner, I temporarily discarded my principles for the sake of some emotional consolation and commiseration and I'm regretful because of it.
