Lyric discussion by wuskin 

I thought it was the beginning of the end of a relationship.

Situation number 1: It's the one that just begun, but evidently it's too late.

I read that as something happened that caused a breakup and it's too late to change what has happened.

Situation number 2: It's the only chance for you, it's controlled by denizens of hate.

I read this as your one chance to kind of plea your case, but it falls on deaf ears of someone who currently hates you.

Situation number 3: It's the that no one sees, all too often dismissed as fate.

This is like when you've both kind of moved on and then you run into each other out of nowhere and catch up. Often the meeting is seen as fateful(?)

Situation number 4: The one that left you wanting more, tantalized you with its bait.

You attempt to reconcile the relationship, but are left with just breadcrumbs of the former relationship.

Maybe it's just me.
