You may not be his first, his last or his only,
He loved before he may love again, but if he loves you now, what else matters?

He's not perfect - you aren't either, and the two of you may never be perfect together, but if he can make you laugh, cause you to think twice, and admit being human and making mistakes, hold on to him and give him the most you can.

He might not be thinking of you every second of the day, but he will give you a part of him that he knows you can break - his heart.

So don't hurt him, don't change him, don't analyze and don't expect more then he can give. Smile when he makes you happy, let him know when he makes you mad, and miss him when he's not there.
