Lyrics:

If he doesn't call when he says he'll call;
Or if he doesn't even call at all,
Well, he just might not be that into you.

If he's too busy to see you on the weekends;
An' he doesn't introduce you to his friends,
Well, he just might not be that into you.

'Cause if he was he'd be hangin' on your every word.
He'd put away his little black book an' put you first.
He'd bein' doin' double back flips to make it work out.

If he's a month late for your birthday,
Or if he calls you by another girl's name,
Well, he just might not be that into you.

'Cause if he was he'd be hangin' on your every word.
He'd put away his little black book an' put you first.
He'd bein' doin' double back flips to make it work out.

Well, if he says he's not the marryin' type,
An' he only calls you in the middle of the night,
Well, he just might not be that into you.

Yeah, yeah.
Yeah, yeah.
I got you now,
Whoa hey, yeah.
You gotta listen girl:
If you're not the centre of his world,
He's not that into you,
Hey yeah.

Yeah, 'cause if he was he'd be hangin' on your every word.
He'd put away his little black book an' put you first.
He'd do whatever it takes to make it work out, yeah.

Well, if he says she's just a friend, like a sister,
Then one day, you see him up an' kiss her.
Well, he just might not be that into you.
Yeah, you just might wanna find somebody new.
Oh, that's what I would do, girl if I were you.

Yeah, yeah.
Yeah, yeah.
Find somebody new.
Yeah, he's not that into you.

Yeah, yeah.
(Find somebody new.)
Yeah, yeah.
(He's not that into you.)
Girl, find somebody new.

(Find somebody new.)
You know you gotta find someone who loves everything about you.
(He's not that into you.)
Somebody: listen now, it's worth it, yeah.
