I don't think he loves me as much as I need?

Well you have to do what makes you happy. Even though you do love him and he probably loves you it seems as though you two may want different things in life. Making it in the entertainment industry is hard so if you do stay with him expect more nights being alone. Either make some friends who you can hang out with while your boyfriend is out and about or try to see if there is someone else out there with whom you can share your heart with. You're still young. Just give it some time.
