seriously please answer... is he cheating!?

Thursday we spent our two month anni together (his idea to celebrate it by cooking for me). We watched part of a movie and he told me that sat we would go to dinner then finish the movie and walk around the park. Friday we spent the holiday w our families. Saturday comes and by 1 pm i dont hear from him. We didnt plan a time but he mentioned something about possibly going out w friends so wed meet early. I figured maybe he slept in and then i got worried something happened. Just as he has done, i texted to ask if we were still hanging out today. He responds two hrs later we can later if im still hungry, but he wont be free until next wednesday after that to hang out.

He made it sound like this was out of the blue when we planned to finish the movie already! Then hours later, when im on my way over there he asks how far i am bc he wanted to go somewhere quick. When i got to his place he was just coming back from some bar and talking on the phone. I said if he wanted to hang w his friends he shldve said that! He says he was going to see first if i was coming over or not. That made no sense to me bc thursday he told me to come over. Then he was all lovey dovey and kept looking at me a lot. Then he wants to make plans for wednesday and thursday (will even take off work that day to spend w me) and when i looked at him funny he asked if i was sick of him. Is his behavior odd?
