It started out, “We got married in high school…” and the only other lyrics I could remember were something about “love come lately…”

I finally found it! It is “Sacred Ground” by McBride and the Ride.

Sacred Ground
McBride and the Ride

We got married in high school
Had a baby when we turned eighteen
I bagged groceries in the daytime
At night I learned to fix TV’s

When you come by things the hard way
Well you learn how to hold on tight
So don’t think you can waltz in here
And take her without a fight

This ain’t just some neon love come lately
Its a precious thing you don’t know nothing about
We were joined in the eyes of the Lord
In the eyes of our hometown
Why don’t you leave her alone
You’re treading on sacred ground

Guess I took for granted
She would never look at someone else
Now I’ve got some patching up to do
Oh, and I don’t need your help

I know you’re the leavin’ kind
Well, I sure hope you will
Before she goes and burns those bridges
That took so long to build

This ain’t just some neon love come lately
Its a precious thing you don’t know nothin’ about
We were joined in the eyes of the Lord
In the eyes of our hometown
Why don’t you leave her alone
You’re treading on sacred ground
Go on and leave her alone
Why don’t you leave her alone
Go on and leave her alone
You’re treading on sacred ground
