Dave,
this is a beautiful, heartfelt love song — simple, pure, and full of genuine emotion. It already feels timeless and personal, like something written straight from the heart (and honestly, it has a wedding vow kind of energy).
Your lyrics look a bit different from what I usually write, which I really like. I noticed you repeat the hook line (“You’re my person”) at the end of each verse. Often when that’s done, a song doesn’t need a separate chorus — but it looks like you’ve included one too. If you don’t mind, I’d love to share an idea for how that could actually work really well together.

(Here’s what that might look like in structure:)

You’re My Person

(Verse 1)
You’re my person
When I think of who I’d call
My heart goes straight to you
You’re my person
The one who’s there through it all
Every joy and trial I go through
You’re my person…
Yeah, you’re my person

(Verse 2)
You’re my person
From the moment we first met
I knew you were meant for me
You’re my person
And I’ve known it ever since
It’s forever — you and me
You’re my person…
Always my person

(Chorus)
I don’t need anyone else
There’s nobody but you
Even when we’re far apart
My love, this much is true
You’re my person

(Verse 3)
You’re my person
The one I promise I’ll cherish
And love in every way
You’re my person
The one I laugh with, the one who
Wipes all my tears away
You’re my person…
Forever my person

(Chorus)
I don’t need anyone else
There’s nobody but you
Even when we’re far apart
My love, this much is true
You’re my person

(Bridge)
Through every high, through every fall
You’re the one who’s seen it all
If the world should fade away
You’re the reason I’d still stay

(Final Chorus)
I don’t need anyone else
There’s nobody but you
Even when we’re far apart
My love, this much is true
You’re my person…
Yeah, you’re my person

What do you think? I really love the heart behind what you wrote — it’s got so much warmth and sincerity. This version just trims and balances a few spots so it flows a little more naturally if you ever decide to record it. Feel free to use any of these ideas.

All the best - Robert
