As English is not my native tongue, I find it difficult if not impossible to understand the last line of Frank Hennessy's song "Start & End With You". I hope there is someone here that can help.
These are the lyrics that I could understand from YouTube.

If I can start & end my day with you,
With a smile in the morning and love to carry me through,
If I should happen to fall, it clearly doesn’t matter at all,
If I can start and end my day with you,

Like the sunshine follows the rain, follows the snow,
As the seasons change, we’ll watch our feelings grow,
And if we have to weather a storm, our love will keep us warm,
Like the sunshine follows the rain, that follows the snow.

We’ll travel along, singing the song, of our life,
Making music, making love,
I need somebody to care, someone to share,
All our joys and all our sorrows, all our tomorrows.

When I see your smile, my sun comes shining through,
When I’m feeling down you know just what to do,
Sometimes I lay awake, I almost hear the cold dawn break,
And I see your smile and my sun comes shining’ through.

I suppose I’m not the smartest fellow you’ve known,
When I gave my love, I gave it to you alone,
Ah you’ll never have an easy live, as a second-rate singers wife,
But my heart is ……

If I can start and end my day with you.
