I'm sure this isn't 100% correct, but I tabbed it out the best I could. Feel free to

Verse 2: (Same as Verse 1)
I'm not the kind of guy who throws himself at
The first pretty shape that crosses his path

To erase all of the remnants of the battle or lines
That we keep reliving instead of forgiving my dear
