I Wore My Heart Out
At one point you will realize that you have done too much for someone, that the only next possible step to do is stop. Leave them alone. Walk away. It's not like your giving up, & 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, & what is not, no matter how hard you try, will never be.
