Tell me what's the reason...that a man's own woman could be so cold
And tell me how the two of you could do what you were doin right in my home
We were supposed to get married...it's kinda scary that we just almost did
I hope that you're happy...cuz you got each other
I don't wanna party your love

[Hook]
You were my best...man, she meant everything to me
She was my girl...friend, closer than two could ever be
You were my best man...best man, yeah yeah
She was my girlfriend...girlfriend, yeah yeah
Supposed to be my best man

[Verse 2]
Should've known when I asked a question, you couldn't even look me in my eyes
no more
Then you start to st-st-stutter talkin bout some "you know better," man hell
naw naw
Tell me how could you...you
Forget about the situation that we've been through
Tell me why, oh why, why
Did you cheat on me, baby...baby, tell me why

[Bridge]
Think about the time (thinkin bout all the time we shared)
Together you and I (I remember when you were my best friend)
What's the reason why (whats the reason why why why...)
