And I don't know what it's called! This is going to be a stretch, but I've heard it like three times.
It's a girl. From what I remember it's an acoustic song.
She's singing about how she misses the guy she's singing to and she hopes/knows he'll find someone new. She says to go down a different road... She regrets not telling him the truth or something. She says she misses him and I think she says she's sorry? I heard it on a Florida radio station. Thanks to anyone who tries to help!

SOUNDS TO ME LIKE YOU HEARD THE SONG, "SOMEONE LIKE YOU" sung by: ADELE
"Someone Like You"

I heard that you're settled down
That you found a girl and you're married now.
I heard that your dreams came true.
Guess she gave you things I didn't give to you.

Old friend, why are you so shy?
Ain't like you to hold back or hide from the light.

I hate to turn up out of the blue uninvited
But I couldn't stay away, I couldn't fight it.
I had hoped you'd see my face and that you'd be reminded
That for me it isn't over.

Never mind, I'll find someone like you
I wish nothing but the best for you too
Don't forget me, I beg
I remember you said,
"Sometimes it lasts in love but sometimes it hurts instead,
Sometimes it lasts in love but sometimes it hurts instead"

You know how the time flies
Only yesterday was the time of our lives
We were born and raised
In a summer haze
Bound by the surprise of our glory days

I hate to turn up out of the blue uninvited
But I couldn't stay away, I couldn't fight it.
I'd hoped you'd see my face and that you'd be reminded
That for me it isn't over.

Never mind, I'll find someone like you
I wish nothing but the best for you too
Don't forget me, I beg
I remember you said,
"Sometimes it lasts in love but sometimes it hurts instead."

Nothing compares
No worries or cares
Regrets and mistakes
They are memories made.
Who would have known how bittersweet this would taste?

Never mind, I'll find someone like you
I wish nothing but the best for you too
Don't forget me, I beg
I remember you said,
"Sometimes it lasts in love but sometimes it hurts instead."

Never mind, I'll find someone like you
I wish nothing but the best for you too
Don't forget me, I beg
I remember you said,
"Sometimes it lasts in love but sometimes it hurts instead,
Sometimes it lasts in love but sometimes it hurts instead."
