You lost me

I am done, smoking gun
We've lost it all, the love is gone
He has won, now it's no fun
We've lost it all, the love is gone

We had magic
And this is tragic
You couldn't keep your hands to yourself

I feel like our world's been infected
And somehow you left me neglected
We've found our lives been changed
Babe, you lost me

Now I know you're sorry and we were sweet
But you chose lust when you deceived me
And you'll regret it, but it's too late
How can I ever trust you again?
