I was looking for 'move-on' quotes and here are some of them that I liked:
One of the hardest parts of life is deciding whether to walk away or try harder.
Moving on is hard.
Knowing when to move on is harder.
I am proud of my heart.
It's been Played, Stabbed, Cheated, Burned, and Broken.
It still works!
You have brains in your head. You have feet in your shoes. You can steer yourself any direction you choose. You're on your own. And you know what you know. And YOU are the one who'll decide where to go...
At some point you will realize that you have done too much for someone, that the only next possible step to do is to stop.
Leave them alone.
It's not like you're giving up,
and it's not like you shouldn't try.
It's just that you have to draw the line of determination from desperation.
What is truly yours will eventually be yours,and what is not,
no matter how hard you try,
will never be.
