My mistakes

I let this happen.
I went along.
I should regret this
I should feel wrong.
I know you used me
I know you changed me
I wish i hadn't
I shouldn't have agreed.
I stayed up late
But trust me, i knew
That night i didn't make a mistake
That night i made two.
You regret me
I regret me too
But from that night
I wanted to continue.
Which should have made me feel wrong inside
It should have made me feel bad.
I wasn't.
I was glad.
But I'm not now
i made a mistake
From now on i know that
From the second i wake.
I would rewind time
and do everything right
But the color from my life would leave
Only black and white.
So tell me now,
did you lead me on?
So i could please you?
I guess you won.
