Let go and trust the universe.
If you love someone, let them go, for if they return, they were always yours. If they don't, they never were.
Sometimes you have to forget what's gone, appreciate what still remains and look forward to what's coming next.
One of the best feelings comes when you finally let go of your attachment to somebody who wasn't meant for you.
Sometimes we have to flight for what we love and care about, but sometimes we have to find the strength to let it go.
