It's interesting that she took that break-up so hard and wanted everybody's sympathy, but after she broke up with Aidan and then found out from Steve that Aidan couldn't function for a month and that he lost his ability to trust women, well, she practically laughed in his face. This from a woman who had to be spoon-fed by Samantha at the resort after Big didn't show up for their wedding. It always seemed to be okay for Carrie to break up with a guy, but when they hurt her, it was some monumental life-altering moment for her. Having said that, not showing up for one's own wedding is a pretty big deal, but she couldn't function for awhile either. She didn't seem to give that same consideration to Aidan.
