"Viper" lyrics

Saw you with somebody
Saw you with somebody else
Why'd you go and do that babe
Looked at me right through the phone and
I can feel my stomach (drop)
I can feel my stomach drop
Said you'd never be the same

Never in my life knew a rose that could feel so heavy
Never in my back felt a knife that could cut so deep

Said you'd never love again you liar
Said it to control my every move
Said you'd never leave - you viper
This why I never trusted you

Grieving on an empty
Grieving on an empty grave
Burying the mess we make

I took you back a thousand times - should've been done already
(How could I say no, and leave)
You told me this was more than anyone would ever love me

Said you'd never love again you liar
Said it to control my every move
Said you'd never leave - you viper
This why I never trusted you

Oh, do her hands touch your skin the way that I did
Bet you fight the same fights like they're new
And you're telling her that you've never felt this
This is why I never trusted you
No one breaks a heart like you do

Said you'd never love again you liar
Said it to control my every move
Said you'd never leave you viper
This why I never trusted you

Hands all over
How d'you know her?
