Tell me not all girls are like this?

I overheard (very clearly) a group of girls talking in school today. One of them, lets call her Alice, thinks she wants to breakup with her boyfriend. Her friends, we'll call Betty and Clare, went on to suggest a course of action

Betty: You definitely should, do it in person and see if he crys, I made my ex cry so much, he got hammered drunk to forget it, what an idiot! And he didn't forget did he?(rhetorical question)

Clare: Yeah, [boyfriend] is a pig, your better off without him. I think you should f*ck him first, and then say he raped you to make some money. You won't have to work at [Coffee Shop] anymore.

Betty: You want his money? That poor bastard couldn't even afford to take Alice to dinner, why did you even go out with him Alice?

Alice: He seemed sweet, but I need to upgrade to a better guy, but how should I break up with him?

Their conversation continued, but I can't stand at my locker forever. I know it's high school, but to say girls just become nice, isn't convincing. Is this how girls talk about men behind our backs. I see women everywhere divorce men to take their money, then upgrade to someone richer, only to take his money. I don't blame women for this, it's free money, and I know men can be horrible people all the same. I just don't know if it's safe to talk to girls about anything real. For any genuine women out there, how many of you are left?
