I can't explain myself at all
And all the wants and all the needs
All I don't want to need at all.
This stanza, I believe is expressing a discontent within a relationship. In this case the male of the relationship is unhappy; this is shown in the first line, saying that he doesn't like the little things about the girl.
The walls start breathing, my mind's unweaving
Maybe it's best you leave me alone
A weight is lifted on this evening
I give the final blow.
This second stanza is saying that after some thought, the guy decides he needs his space, and by her leaving him alone, he feels much better. I believe that the final line "I give the final blow means that he broke up with her officially.
Light
It ends tonight, it ends tonight
A falling star, at least I fall alone
I can't explain what you can explain
You're finding things that you didn't know
I look at you with such disdain
This is the third stanza and again the male in the relationship is expressing discontent in the relationship, saying things like I look at you with disdain, is a major red flag in a relationship.
The walls start breathing, my mind's unweaving
Maybe it's best you leave me alone
A weight is lifted on this evening
I give the final blow
When darkness turns to light
It ends tonight, it ends tonight
Just a little insight won't make this right
It's too late to fight, it ends tonight, it ends tonight
Now I'm on my own side
It's better than being on your side
It's my fault when you're blind
Its better that I see it through your eyes
All these thoughts locked inside
Now you're the first to know
The fourth stanza is pretty much giving reason for the breaking up of the girl in the relationship. By saying it's my fault when you're blind; it's saying that she doesn't fully understand him.
When darkness turns to light
It ends tonight, it ends tonight
Just a little insight won't make this right
It's too late to fight, it ends tonight
This is the chorus of the song and it is saying that it can't be changed, that the relationship is over, that there is nothing else to say, it’s over.
It ends when darkness turns to light
It ends tonight, it ends tonight
Just a little insight won't make this right
It's too late to fight, it ends tonight, it ends tonight
Tonight, inside
When darkness turns to light
It ends tonight
