Is it normal that my long distance boyfriend was selfish?

Ok, so this past summer I met a guy while backpacking Europe and we really hit it off. He lived in Canada and me in the US. After the trip we continued to email everyday and after two and half months I flew to see him and spent 9 amazing days with him, getting to know him, his family and friends. We both agreed we could see this being long-term and tried an LDR. In the beginning he would write me love emails all the time and we would skype constantly, but that kind of died down. We got in a few spats over communication issues, but eventually we resolved it and things for the most part were really good.

The plan was for him to visit me in December and since I did not want to wait 4 months I propsed a long weekend in Vegas. He agreed, and invited his sister and her boyfriend. We were all really looking forward to the trip. When we got there we were both super excited and the first two days were full of going out and having fun and spending the day laying in bed together, etc... I knew he liked to gamble and even though it is not really my thing I would come watch him do it. Also, him and his sister are really close which I noticed, but it did not bother me until the 3rd day, when he started ignoring me when she was around and directing every question/statement to her. This is when all the problems began. He would put on sports on the TV when I proposed we watch something together (I don't follow sports), he tried to go to a topless burlesque show with his sister that I had already seen and did not want to see again, he made plans to go see UFC at a sports bar without asking me what I wanted to do, etc... He got annoyed at me for asking if we could shut off the TV and play cards so we could hangout etc... I tried to be accomodating to him and would ask questions about sports and gamble with him and went to the UFC match without complaining, I offered to see a comedy show instead of the show I had already seen, etc... but he basically made me feel like I ruined his trip. He also made a comment like "You didn't have money to see the burlesque show but you had money for an expensive dinner you planned for us?"...the point was I had seen the show before and didn't want to see it again. There was an exhibit that I really wanted to see at our hotel that he had already seen and he said he would go with me, but I ended up going by myself even though I offered to pay for him.

My point is, am I wrong to think that in a long distance relationship after not having seen each other for 2 months shouldn't the trip have been more about spending time together and less about sports/topless woman? I was sick on the last day yet I still walked the strip with the rest of the group because I knew he hadn't seen it yet. They drank beers the whole time while I chugged pepto bismol and he barely spoke to me.

Has anyone else had experienced like this?
