What part of the game is this

-Chorus-
What part of the game is this? You changed with all your selfishness/ What happened to our happiness/ I just wanna know how the game go and why you're changing up on me

I loved you from the moment that you walked in the room, the chemistry was real and we was so in tune/ When you wifed me I took the background to your foreground/ Yeah, I supported all your dreams and I stayed down/ Even when I caught you with that chicken, tried to kill your ass and my love was still deep and I forgave the past/ And I'm bout to ride wit'cha, never let 'em get'cha/ And through the thick n' thin I'm down to down wit'cha/ Now, I'm focused on my dreams and I'm workin' for mine/ Now you hatin' from the side givin' me a hard time/ Said you want your girl rappin' you just want me at home, what? You jealous of my shine cause my stash has grown? You all rollin' up on niggas tryin' to stop my flow, wilin' out up on my sessions tryin' to stop me dough/ Even though I'm ridin' wit'cha cause you know you're my man, but I'm guessin' my success wasn't part of your plan/ What the deal?

-Chorus-
What part of the game is this? You changed with all your selfishness/ What happened to our happiness/ I just wanna know how the game go and why you're changing up on me
