美国女歌手Rihanna最近专辑A Girl Like Me的歌～Unfaithful...

楼上的歌词漏了第一段～汗～

Unfaithful - Rihanna - A Girl Like Me

Story of my life
Searching for the right
But it keeps avoiding me
Sorrow in my soul
Cuz it seems that wrong
Really loves my company

He's more than a man
And this is more than love
The reason that this guy is blue
But clouds are rolling in
Because I'm gone again
And to him I just can't be true

And I know that he knows I'm unfaithful
And it kills him inside
To know that I am happy with some other guy
I can see him dyin'

I don't wanna do this anymore
I don't wanna be the reason why
Every
