What Does this Mean

I told my husband I no longer am happy. I told him that I feel he is emotionally absent. He yelled at me that he is a good husband because he paid $500 in groceries. He wished me luck on finding another man to do that. I told him that him buying groceries had nothing to do with our discussion. That other men buy groceries too. That he eats those groceries and I cook for him. So congratulations for feeding himself. When I continued telling him I feel he is absent from our relationship, like he doesn’t want this, he told me he doesn’t want to fight so he would stay silent. I asked why he can speak up about how much money he spends but not on why is emotionally absent from me and our relationship, he continued to stay silent. Why can he throw money in my face but not explain to me why we don’t sleep in the same bed or why we don’t have sex or even talk to each other anymore. I feel he is cheating but I have no proof and I honestly don’t care anymore. I am ready to walk away. What does his response to me mean?
