At some point , you realize that you have done too much for someone or something, that the only next possible step to to do is to stop. Leave them alone. Walk away. It’s not like you’re giving up, and it’s not like you should not try. It’s just that you have to draw the line of determination from desperation. What is truly yours would eventually be yours, and what is not, no matter how hard you try, will never be.
So, keep people in your life who truly love you, motivate you, and make you happy. If you know people who do none of these things, let them go.
Some time, you just need to distance yourself from people. If they care, they’ll notice. If they don’t, you know where you stand.
When all said and done, the one is lonely. Always remember that.
