Affiliate Marketing Secrets

he bought me a car im 21 hes trying to control my life thorugh the car can he legally take it away if i pay for insurance and the insurance and registration is under my name? i asked him for the papers of the title and he doesent want to give it to me because then, i will have the full paperwork for the car why doesent he want to give me the title paperwork? if the car is under my name then the title should only be under my name too? is it possible for him to have some say in the title? the car is under my name ONLY NOT HIM. so the title only belongs to ME right??? he cant be affiliated in the title? i checked the registration n insurance and its only me.
