Am I wrong?

I went upstairs to talk to my husband. He made a comment about us making love tonight. I said sure and he said tomorrow morning. He figures he can enjoy his beers tonight since he's missing the game tomorrow. We had an agrement to not drink during the week because beer is expensive and I don't like sleeping with someone who has been drinking. After I was done talking, I asked him what he thought and if he had anything to say. All he said was that he was feeling like he was getting lectured. I'm extremely frustrated because I'm making a lot of sacrifices and he seems to have trouble making small ones like not drinking during the week or just drinking two beers. I told him that he was being selfish for spending our grocery money on extra beer,etc.etc.
