If your boyfriend treats you with respect; you date during the weekend; he calls you a couple of times a week then he does care for you. It is not healthy to be seeing each other on a 24/7 an hour basis. Each partner should be independent of the other to a degree. You should be seeing your girlfriends and having some fun and he should be seeing some of his male friends. If he does not treat you as mentioned above then you need to tell him you are unhappy about certain things as communication with your partner is even more important than sex. If he refuses to change and give you more of his time (fairly) then you need to move on from him.
