I am 20 years old and i am still leaving with my parents. ?

i don't have a room, I go to a private college and it costs a lot of money. My parents don't want me to move out until am ready to get married other wise they would start talking felling unlucky with kids. The bad part is i don't have a room and my bed ,my working table and chair is seating in the living room which cause me to have no privacy. I don't know what to do any more.
