Is it over or is it just a relationship stage?

My boyfriend and I have been dating for 1yr 5 months now and I feel so tired of him. I never feel in the mood for anymore, or like going on trips with him and his family. He was going on a 3 day trip with his father and sisters and all I could think about was how can I get out of this. He is a handsome guy and we get along very well and have good conversational chemistry, I just dont ever feel like having . Last night we went on a date to the Olive Garden and hung out at the mall and when we came back, went to my room and he wanted to go straight to business but I wanted to fool around some more and he took it as an insult to the way he does things. I thought communication was supposed to be key but he was just upset that I was "practically" telling him what he was doing wasn't good enough. I don't know what to do. He seems like the kind of guy you marry and have a family with and I may never meet anyone I'm more compatible with, but I dont feel anything for him anymore. Is this just a lull? A stage in the relationship phase?
