"I can't imagine you with anyone else"
I can imagine someone else.
Eventually he'll be tall and maybe he'll be blonde, but no matter what he'll look like I'll love him just the same. He'll be quiet I'm sure, but he'll always be listening. I'll hold his hand, keep him safe, and comfort him when he needs me. Cradling him in my arms, I'll feel a love more pure than I ever knew existed.
But he can wait. I want you to myself for at least ten more years. Even then, I'll love you more each day than I did the day before.
In time he will be another piece of my life, and evidently a piece of yours. When I'll look at him, all I'll see is you in his smile, his eyes, and his laughter. I can only hope not to see parts of myself in him, too. I'd much rather he be the spitting image of you than at all noticeably related to me. Even if he looks like me, grows up like me, or thinks like me, I'll always know he's part of you, too and I'll think of you and your stormy irises every time I look at him. I'll stare in amazement at the most beautiful boy I've ever seen and I'll thank all the stars in the universe that he inherited his father's eyes and not mine.
