He's not perfect. You aren't either.
And the two of you will never be perfect. But if he can make you laugh at least once, it causes you to think twice. And if he admits to being human and making mistakes, hold onto him and give him the most you can. He isn't going to quote poetry, he's not thinking of you every moment, but he will give you a part of him that he knows you could break. Don't hurt him, don't change him, and don't expect more than he can get. Don't analyze. Smile when he makes you happy, and miss him when he's not there. Perfect people don't exist, but there is always one guy who is perfect for you.
