Be with someone who knows exactly what they have when they have you. Not someone who realizes it after they've lost you.
Be hard to find someone else. We were friends first, then she became my best friend, my closest friend. Then she became the love of my life. My whole world.
So if you feel happy with someone, regardless of how much fear of being hurt you have, you should tell them.
Be with someone who honors you openly and when no one else is there.
So many take what they have for granted. While someone would do anything to have the very same person. I say get out if they don't appreciate you.
