Be with someone who loves you and shows it to you. Every single day.
If someone truly loves you they won't judge you by your past, but instead try to create a future with you.
If someone loves you, love them back unconditionally; not only because they love you, but because they are teaching you how to love and open your heart and eyes to things you would have never seen or felt without them.
When you really love someone you develop a sixth sense for them. You can feel everything they do. Like when they're in distress, when they're happy, when they're lying. It's the weirdest thing, but it's a real thing.
