Bored. :-/
might not be his first, his last, or his only. He's cared about someone else before and possibly will again, but if he cares for you now, then what else matters? He`s not perfect and you aren`t either, and the two of you will never be perfect, but if he can make you laugh atleast once, hold onto him & give him the most you can. He is probably not going to quote poetry, he might not be thinking about you every second of the day, but he will give you a part of him that he knows you can break. So don`t hurt him, don't change him & don`t expect more than he can give. Don't over analyze, smile when he makes you happy, yell when he makes you mad, and miss him when he`s not there.
