Who he is

You aren't going to be his first, his last, or his only. He's loved before and will again, but if he loves you now, then what else matters? He's not perfect; you're not either. But if he can make you laugh at least once, cause you to think twice, and admits to being human and making mistakes, hold on to him and give him the most you can. He's not going to quote poetry, he's not going to be thinking of you at every moment, but he'll give you a part of him that he knows you could break.
Don't hurt him.
Don't change him.
Don't expect more than he can give.
Try not to over analyze.
Smile when he makes you happy, yell when he makes you mad...
And miss him when he's not there.
