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.
