Boyfriend is being distant

Any advice for how to deal with your SO being distant? We usually see each other everyday and this whole past week we haven't seen each other at all. He barely texts me and he isn't saying a lot when we do. It's really hurting me and I need advice. We got into a small argument the other day about something that he did and I think I annoyed him when I was trying to tell him how I felt. I feel kind of lost. It is a young relationship because we have only been dating for a couple months. What should I do?
