The only reason I stay is because you need me too. You need a friend to be there since everyone else just wants to use you and get in your pants and dont really care enough to know you I am playing that role yet still being in pain and no love or help for me. 
You will toss me aside one day but I don't care, I am that good of a person. You treat me like shit make me feel like shit but I am beside you all the way. You tell me things that make my insides crawl and make me want to die, but I put of a brave face and stand by you. You wont care in the future you will toss me aside and I will once again be lonely. It proves what good people get in this world doesn't it?
