Husband got mad at me

My husband is upset because I didn’t want to suck his dick. We were planning on having sex but quickly went sour when I told him no to giving him head. Only simply because I wanted him to wash up but he didn’t want too. It’s been a week and half since we last had sex. At one point we didn’t have sex for over a month. He opened the condom wrapper, but I simply told him no over again on oral sex. He was upset and basically threw the empty open condom on me. Right ?! How disrespectful! I felt like he slapped me and disrespect me on so many levels. Looks like we are sleeping in separate rooms tonight. I honestly don’t even want to speech to him. Am I wrong for how I feel? How do I go about setting boundaries?
