You don't need put yourself into a restless situation. You can help without attachment and expecting returns from other people as a compensation for your deeds. You can even care for them, why not? but never expect anything... "Help then Forget" so you will not get hurt.

Always put in mind that people have different attitudes and characters. Expecting too much will definitely give you disappointment and possible lead you to revenge.

Caring is about giving what you have,.. it's love! A love that's not conditional.
