Something is off

My husband and I don’t use condoms . We are going through the lows of our marriage. We are on the brinks of divorce . Tonight we impulsively decided to go to the movies .. which we haven’t been in 2 years. Sex is pretty much non existent.so we are Laying in bed. He pulls out a condom and ask do I want to have sex … I’m honestly appalled because why do he have condoms .. and I asked that. He couldn’t give a answer rather than just asking do I want to do it or not . He got mad because I asked him to answer me first . He says nvm I ruined the mood …. Am I being blind or is something going on that I’m not realizing ???
