I think it is important to know that you don't have the answers. Your bf is not communicating to you very well. Clearly he has some feelings and/or thoughts that he is not telling you about.

You might want to back off just a bit. Not that you have done anything wrong. But just in case he is feeling claustrophobic. Then ask him after the weekend what is going on? He has all of the control and that is not a comfortable thing for you. You are in a totally wait on him mode. That isn't right. SO -- if for example he doesn't spend next weekend with you either, and he doesn't tell you wnat is going on, make your own plans for the weekend. Do not allow him to control your time. You are not just sitting around waiting for him to decide whether he wants to be with you. You will be living your own life.
