I agree. I am not sure that she "isn't a friend". Some people are REALLY thick and just don't think. I have a relative that I love to death. She is a good person, is wonderful to me and to my family, gives great advice, etc... HOWEVER, once in a while she says things that she does not realize are hurtful. Yes, she can be dense... I tell her every time and she always gets it after the fact. Everything else about her far outweighs the few stupid things that she does... I think you should tell your friend exactly how stupid and hurtful that she was. Does she do this sort of thing often? If she does, that is a BIG RED FLAG... Otherwise, give her a chance to say why she behaved like such an ass... At the very least, you will get this whole incident off your chest.
