No, he just tried to turn the nurse into a girlfriend type, when she was really just a slut that only wanted to fuck... he was trying to wife her up, and that was her way of letting him know that she lost interest as soon as he tried to turn it into something "real".I don't understand that shit at all. It's not like it's difficult to set an alarm or cancel the morning of. And it isn't that people like that are "flaky", it's that they are inconsiderate shitheads. That's a real jimmie rustler.
This is pretty much the reality of dating most women... Just don't ever show them that side of you, and you should be good and the flaking will stop.
