Sentido de la música

Hace poco,he descubierto otra música de Three Days Grace del álbum Life Starts Now.Se llama Last to Know(último a saber)y,entendiendo la letra llegué a una teoría.

Letra:

She just walked away
Why didn't she tell me
And where do I go tonight
This isn't happening to me
This can't be happening to me
She didn't say a word
Just walked away

You were the first to say
That we were not okay
You were the first to lie
When we were not alright
This was my first love
She was the first to go
And when she left me for you
I was the last to know

Why didn't she tell me
Where to go tonight
She didn't say a word
She just walked away

You were the first to say
That we were not okay
You were the first to lie
When we were not alright
This was my first love
She was the first to go
And when she left me for you
I was the last to know

I'll be the first to say
That now I'm okay
And for the first time
I've opened up my eyes
This was my worst love
You'll be the first to go
And when she leaves you for dead
You'll be the last to know

Para mí no es lo mismo que creen todos,un hombre sobre la mujer que la ha dejado y hablándole,sino el hombre culpandole al mejor amigo de la mujer,pues hay una parte que dice que le ha cambiado por otro.Para mí,además,quiere decir que gracias a que le mentió a la mujer la mujer le dejó al protagonista.
Es algo triste,pues según el final,dice que cuando muera la mujer,el "amigo"no lo sabrá.Y significará que él no la quería,y que sólo quería partirle el corazón a los dos.

Parece en factos reales,y no del cantor,pues eso es algo que hoy en día es común.

Dicho esto me despido.
Saludos,Persona B.
