my boyfriend is distant and it's scaring me

so my boyfriend is 20 and I'm 17 (both of our parents approve of our relationship) I used to live where he currently lives and recently moved where my mom lives before we started dating. we've been dating for almost 4 months and I feel like he's getting tired of me. we have a active sex life, we both get along, and the only time I have a problem is when he thinks that it's okay to walk all over me. He never does anything with me. all we do is sit home and watch movies, we literally never go out and enjoy the weekends. I waste gas I feel like coming to see him because it's like he doesn't enjoy my company. when I tell him he pushes the topic away. any advice on what I should do??
