How can i get him to cater to me a little bit?

i love him hes amazing, but he just wont do anything for me anymore. like i asked him to walk just outside with me cuz it was dark so i could grab my purse off the porch....and his answer hell no i aint walkin. and i do everything for him. its nothin huge i jus wish he'd do things like not make plans with his friends when im with him and leave me stranded at his moms house while hes out drinkin and smokin pot...i ask him not to make plans bc i was leaving for a wekk and i wanted to spend a little time with him b4 i left...his answer ill try but ill prlly forget. jesus, how do i get him to care?
