The best love is the one that makes you a better person. Without changing you into someone other than yourself. Real love doesn't love someone else or who they think they can make you, they love you as you are and try and make you better!
Don't let someone who did you wrong make you think there's something wrong with you. Don't devalue yourself because they didn't value you. Know your worth. If you have a couple solid people in your life you can trust, you're golden.
