Analysis of This I vow.

In the shadows, I stand, not the first to love you,
But the last, I aspire to be, to cherish and hold true.
I may not have been the first to make your heart sing,
But I long to be the only one to make it forever ring.

To be better this time and respect you every single day,
To be your lover and your friend, come what may.
I'll listen, I'll share, and I'll always be kind,
For you are the only one who occupies my mind.

I love you, I'll always love you, this I vow,
You are the only one I'll ever love, then and now.
In your laughter, in your tears, I'll always be near,
To love you deeply, to hold you close, my love.
