you have to draw the line

At some point you will realize that you have 

done too much for someone or something, 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 would eventually be yours, and what is

not, no matter how hard you try, will never be.
