I asked her if she wanted to this some other time because I'd rather not go anywhere with her at all than to put up with her rudeness.
I'm pretty sure that set the tone. Something cruddy happened to her and she was upset about it, and to add insult to injury her "friend" wants her to put on a happy face and STFU so that her "friend's" night isn't ruined.

She didn't handle herself well, but it sounds like there are equal amounts of rudeness going on here.

As to whether all women are moody, I don't think so. I do think we might show our feelings more than you're comfortable with, but that's not being moody. When something bad happens, it's NORMAL to react.
