You wont be his first, his last or his only. He's loved before, he will love again but if he loves you now what else matters? He's not perfact, neither are youand the two of you will never be perfact but if he makes you laugh, at leas once cause you to think twice, and admits to being human, and making mistakes. Hold on to him, and give him all you've got, He's not going to quote poetry, he's not going to be thinking about you every moment, but he will give you a part of him, that he knows that you can break. Don't hurt him, don't change him,don't expect to much from him. Smile when he makes you happy, cry when he makes you sad and miss him when he's not there. :)
