I've made this mistake a bunch of times. Where you give so little fucks that they actually dump you.
My opinion is that it's okay to do some favors for girls you want to keep around, or ones you're actually friends with. If you truly don't give a fuck, do nothing but they'll eventually dump you.
It's different if you're doing favors for a chick in hopes of getting laid, because it will never happen.
It's one thing not to be a doormat. However, when you're a total unrepent douche with chicks you're banging, it makes them feel like slam pigs.
