Not very easily... But there is always someone else out there who you will learn to love just as much.
You don't need his permission to go. If he doesn't love you, there is no way to make him love you. Don't stick around because you think he will change.
let time heal it, dont worry yourself over it, and most of all dont let it control you find new love, not a replacement
you let them you easy. For Example go to dinner and them let them down easy.
realize that they are not the only person out there and accept the facts
