Why do I try?

There have been times when I thought to myself
"Why do you try?"
No matter what, I'm the same old guy
The one who loved you without control
The one whose heart has a gaping hole
I used to say to you
I'll never leave you
I won't lie to you
I'll always tell the truth
I kept my promise and didn't lie
And won't until I die
But it just seems as if
I can't live without you here

Why do I try?
You're off with some other guy
I'm here left to think of the past
Of how we didn't last

There have been times when I thought to myself
"Why do you try?"
No matter what, I'm the same old guy
The one who blindly loved you
The one who once flew the moon
But now whose heart is through

Why do I try?
You're off with some other guy
I'm here left to think of the past
Of how we didn't last
Why do I try?
