boyfriend compares porn addiction to my depression

I'm not really sure what to say to him anymore. Everytime I try to explain why I am hurt and angry about his addiction to porn and pictures of naked women and, he always compares it to my depression. When I try to tell him how angry I am about him sexting other girls he compares it to my suicide attempt that happened before we were dating. I'm so sad about this. I never know how to respond. it's not the same but he will never understand.
