I'm done doing it all alone.....

I do everything in our marriage and our home. My husband could never handle even one day in my shoes while I'm cleaning or cooking or taking care of the kids he is watching TV, getting a moment of silence outside (I wish u could do that), or off with his buddies playing softball. I am constantly taken for granted. A year ago I went through a really hard time with anxiety and depression Instead of manning up and helping me through he started a texting relationship with some woman in another state. We went to therapy to fix our failing marriage and it all seemed great for a time. But he doesn't talk about anything and leaves me to start the conversations and then makes me feel like I'm interrupting his important life with my petty issues. When I finally lose it he will actually tell me how he feels but it doesn't feel real. It feels like made up feelings meant to shut me up. He suffers from his own anxiety and depression, but unfortunately he suffers in silence and doesn't talk about it much I'm done but I also don't want to be alone.....although I kind of am already. Am I completely insane to hope he finally makes it all right?
