There's a Reason for the Longing in Your Heart ...
A famous poet (I don't remember which one) once said something like "Love only seems to disappear so that you will seek it again." It's kind of what I'm saying.
Life is too short -- and too long -- to live without love. I love you and it would be sad for me to think of you going through life in sadness and longing when the whole point of life is LOVE. A soul was meant to love and love is all there is. Don't spend the rest of your life looking backward when love is waiting ahead of you. Allow yourself to heal and you will once again experience a love like you've never had before.
Life is the school. Love is the lesson. Love is the Teacher too.
