The production sounds like Gabriel and Dresden but there's a lot of vocal in it and I've checked the latest G & D stuff and it doesn't seem like this is on their list.

I shoulda been there, but i was gone
I shoulda been there, but i was so wrong
I shoulda been there, but i was gone
I shoulda been there, but i was so wrong

Seeing a reflection of me next to you (???)
Guess it was all i thought you needed
I was wrong for leaving so long
I was wrong, I was so wrong...

Why didn't I just keep you near,
Now that you're gone I feel so-ooo alone.

I shoulda been there, but I left you
I shoulda been there, didn't forget you...
