You know I take care of you Whatever you need I'll do Ungrateful, look how you repay me Unfaithful, look how you be playin' With my heart (Oh..) You have no regard I swear, if you keep on doing me wrong You'll look up and I'll be gone I thought we were past these days No more games, I believe So now what I hate the most, is you think you're so smart You think you're foolin' me [Chorus] Oh, you must be Dumb, dumb, dumb; I ain't Dumb, dumb, oh baby, you so Dumb, dumb, dumb; I ain't Dumb, dumb, no, no, no [Verse 3: Meek Mill] I say, you know I know I ain't right But I know you know I ain't wife No other chick but you shawty, I ain't trippin' off you shawty Heard I'm in my old hood, but I ain't trip when you party Love hurts and I feel your pain, through all the fame, I still remained The same n***a, I did, then I came home and I still explained All this sh** you heard about, you gon' let these hoes come steal your lane Or you gon' let it just die on me, hold it down and come ride for me [Bridge: Jazmine Sullivan] Now if my tears don't mean nothing Don't insult me with lies And if you won't never change Please stop wasting my time Cause if you wanna go out and be single Go 'head, I told you I won't beg Cause I know you gon' miss me So if you leave, baby, you must be [Chorus] Oh, you must be Dumb, dumb, dumb; I ain't Dumb, dumb, oh baby, you so Dumb, dumb, dumb; I ain't Dumb, dumb, no, no, no
