Ya know, she might be like that with everyone... some people just suck at returning calls. I had a friend whose boyfriend eventually broke up with her because she'd be busy when he called, and she'd always forget to call back.
Then she'd wonder why
he wasn't calling her. I always had to remind her that he
did call, like an hour ago, and she blew him off. Some people are just like that.
But that's only the case some of the time. Most of the time, this type of girl is an inconsiderate b*tch who's not worth hanging out with. If you call her again, you'll look pathetic. Play it cool, as if it's her problem if she doesn't call you. Because it
is, isn't it? As if life isn't inconsistent enough on its own, you need unreliable friends, too?
