I learned a long time ago to quit expecting things from people and that way you can't ever get hurt. The words are true. But never getting excited about anything makes for a sad life. So in the end, which way is really better?
It's not about finding someone who won't fight with you or make you sad. It is about finding the person who will be standing there wiping the tears away, holding you in their arms after a fight. The one who will never leave, no matter how hard it gets.
