you didn't expect that lyrics

I was your man, you were my girl
Would have given anything to you in this world
So, why is it lately you've been acting cold to me
You don't want to talk to me, you don't like my touch

So, tell me why would you do this?
Could have told me so, I'da let you go
Look how it ends
We can't even be friends

When you cheat, when you lie, when you kiss me goodnight
You didn't expect that I would find out
When it's late, when you say you were at your friend's house
You didn't expect that I would find out

So many little things keep on adding up
Girl, I've had enough pretending that I'm blind
Two way blowing up way past twelve o'clock
Let me tell you what, it's about that time

And yesterday, I followed you baby
I know where you've been, I saw you with him
Look how it ends
We can't even be friends
