Dressed up, at the bar You showed up 15 minutes late 'Cause you thought, that you'd be The one to make him wait Now you're sure he's got a good reason You're sure he'll get there soon So you're ordering another drink And acting like it's cool! That he says he doesn't want something serious And you tell yourself you like that he's mysterious He's just busy, on the go and His stupid phone is broken and You say it till it almost sounds true But he's just not that into you He's not that into you So good, at disappearing That he's almost like a ghost And it's anybody's guess Where he's been and where he goes I ain't saying he's a liar But he ain't telling the truth And he's as good at making out As he is making an excuse Like when he says he doesn't want something serious And you tell yourself you like that he's mysterious He's just busy, on the go and His stupid phone is broken and You say it till it almost sounds true But he's just not that into you He's not that into you Oh, he's hung up on his ex He never got your text He's gonna say he's sorry and you're gonna forget That he says he doesn't want something serious So you tell yourself you like that he's mysterious He's just busy, on the go and His stupid phone's still broken And you say it till it almost sounds true! That he says he doesn't want something serious And you tell yourself you like that he's mysterious He's just busy, on the go and His stupid phone is broken and You say it till it almost sounds true He's just not that into you Oh baby, I've seen it But I've heard it too He's just not that into you He's not that into you He's not that into you baby He's not that into you I hate to break it to you But he's just not that anymore into you
