Should've Known

I know you gave me your everything.
But it never was enough.
I know you'd ask how high,
If I told you to jump.
But you started out as Wifey.
Then moved down to Friend
'Cause you gave up what was ours
And for that, my heart still mends.
The past, I never forgave.
My trust never will come.
But I can't even keep it in any longer,
I must confess you weren't the only one.
She was here at my place
When your excuse was rain.
She was here every single day
I couldn't stand to hear you complain.
She was here, as you laid in that clinic.
She's the reason I couldn't go with you.
She's the reason I can't pay to take you out,
And that you always have to.
When my phone was on 'vibrate'
And I only got to it at the last ring
Here she was, by my side,
Making me feel like a king.
And when I say I love you
You must know that wasn't a lie
But your love was never enough
But please, please don't cry.
It was over before it started.
I know you checked my emails
You thought I left them by accident?
But all you said was 'Oh well'.
I know you sat there wondering
Why Moms didn't return your call.
She already knew about Her
So she saw no point at all.
I'm sorry you're the last to know
But I gave you lots of signs.
But maybe next time you should learn
To read between the lines.
Hell, I'm not too busy
Nor am I too stressed.
But she's tired of being second
So now she'll have my best.
You should've known from day one
That this wasn't going to last.
She's been here all along
And we've been going nowhere fast.
And you're probably sitting there crying
Saying 'She can't do what I do'
What you don't see is that if I wanted that
Then I'd still be with you.
So wipe your tears away
And stop calling my phone.
Now at least you can tell yourself
'Shit, I should've known'
