In the back of a subway

You said the closest thing you had to steady sex was spreading a girl's legs in the back of a subway
You said you are more fucked up than you lead on
And then you said you wouldn't leave me

You said these things and I listened
And suddenly the grey dome sky didn't feel so claustrophobic

But now you're having steady sex
but it's not with me
You spread her legs but her legs aren't mine
but I wish they could be

You said you wouldn't leave me and I can't help but wonder

Do you tell her you won't leave her?

Do you tell her the closest thing you had to steady sex was spreading a girl's legs in the back of a subway?
Do you tell her you are more fucked up than you lead on?
And tell me, do you tell her you won't leave her?

Or will you leave her like you left me?
