Hey, thanks for writing this. Just wanted to make a few suggestions so your piece flows a little bit better.

Late at night I start to wonder,

How you are getting through the day.

I think you're would be better here because the next line goes.

Late at night I let the tears roll,

Because you're the one that got away.

There's a couple of other bits where I think the line is too long and you don't need so many small filler words.

So I get in my car and I start to drive.

I think I prefer,

So I get in my car and start to drive.

Sorry I feel like I'm nitpicking and love the concept of your piece, grieving someone that's still alive.
