Help?

I'm 20 and live with my boyfriend of 3 years. We met in 8th grade and are basically best friends but this past year he's just been super controllive and its making me insane and more attached to him.. I love him and don't want to leave him. I'm turning 21 in august and told myself I want to find out who I am and what I want to do.. I don't know how to drive, unemployed, and really want to go to college. Our relationship is just fights and arguments it makes me unmotivated so I don't bother to try and change anything. I don't have any friends. I feel stuck and hopeless and way too young for this
