you might not be his first, his last or his only. he's cared about someone else before and possibly 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 he can make you laugh at least once, hold onto him and give him the most you can. he is probably not going to quote poetry, he might not be thinking about every second of every day, but he will give you a part of him that he knows you can break. so don't hurt him, don't try to change him and don't expect more than he can give. don't over analyze (because every girls tends too) smile when he makes you happy, yell when he makes you mad and miss him when he's not there. it's that easy.
