I personally think that this is the problem with women, or should I say girls. Nowadays, every female I run across (I am 24) truly believes (due to the way society has been running) that she deserves attention and affection from men, by natural right. And when she doesn't get it, the man is being insensitive or selfish.
You just summed it up, stating that "the reason we leave is because we feel lonely...neglected". Does this not seem immature to anyone else? That is how a child acts when others are not playing with them at the playground. I, personally, have come to the end of the rope with females today. I can't imagine ever finding a girl my age that is strong, confident, dependent, and doesn't hide behind the excuses that "society" (I know, it's cliche) makes for her.
