Well obviously every wants someone who cares about them, isn't that a basic requirement for a relationship?(bare in mind people go into a relationship under the impression that someone cares for them, if they find out later that's not the case then that's a whole other situation, but people do go into relationships under that pre tense).
Mind you its not the ONLY requirement you need (but its a necessity.) Being a "kind hearted person, always willing to help, polite and caring" is just a description of a decent human being, so you're not going to "stand out" as it were with those qualities. Not saying you should stop being a decent human being because that wont help you at all) But realise that you may need to have more going for you.
I'm not sure where you're reading that girls like to be treated badly, but they don't. No one likes to be treated badly in a relationship.
