Happy Love Poem?

Why am I still here, you ask?
Well, explaining that is no simple task.
I can tell you one major reason was Michael.
I was in love from the first smile.
No, it wasn't romantic love I felt for him.
But it was love, and it filled my heart to the brim.
Holding his small hand in mine,
Watching how his eyes would shine.
Though he was my nephew, I loved him like he were my own son.
If not for him, who know's what I'd have done.
Two years later, he still lights up when he sees me.
He is still the most beautiful thing that I'll ever see.
I owe him more than he'll ever know.
I love him more than I could ever show.
