I think that (after listening to it quite a lot) it's about a broken marriage "Try to kill a broken vow"
The (probably) wife of the guy wants to end the marriage and forget everything they shared together but the guy doesn't want this.He's in denial because he still loves her and that no matter what,he'd still be there for her "Cause I'll still be here when you see,Your not alone".

Anyways,that's how I understand it.
