Look inside yourself and find your flaws. Learn to change what you can, and make peace with what you can't. Find your strengths, and stay humble about them. Otherwise, you'll never be happy with anyone. It's your fault, learn to deal with it. Just saying.
and lord knows that's all I ever did. I could never be a good enough friend in your eyes and if I would have known then the things you would be doing to me now I would have told you to kiss my ass all the times you got mad at me for no reason at all
