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. Walk away. 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.
No matter how much you have tried, no matter how much you care, no matter how. much it has cost, there comes a time in a relationship when the only option left is to set the dumb beast free that won’t be tamed. Both will then be able to move on with their lives
If you've ever loved and lost love, then you will understand that you need to learn to love yourself as much as you need to let go of that person who no longer loves you, so that you can move on, be happy and allow yourself to love again.
You can't ever let go of all the feelings, But you need to let go of him.
