am i insane?

I don't know half the people at this party
So I keep staring at my phone
Talking to a stranger just to fill an empty space
Of course I feel alone

Then you go and show up with him
You're making out that you really want it
Making out but you're looking at me woah
It's messing with my head

Am I insane?
Did you touch my hand when you passed me?
As you were walking to the bathroom
I know you're leaving
But I don't know if you mean to leave with him or me
I can't tell what you're thinking

You move a little closer and you whisper in my ear
I wonder if he knows
And the thought of us excites me
I've undressed you in my head
I wonder if it shows

Then I blink and you're back with him
You're making out that you really want it
Making out but you're looking at me woah
It's messing with my head

Am I insane?
Did you touch my hand when you passed me?
As you were walking to the bathroom
I know you're leaving
But I don't know If you mean to leave with him or me
I can't tell what you're thinking

Am I insane?
Am I insane?
Am I insane?
Am I insane?

Maybe I'm just insane
Would it be better if I never showed my face
And I never heard your name again, oh god
We never even tried
