I am sorry for your personal problems and your marital problems. But I am not convinced that your remarks about your wife are an accurate assessment. My husband used to say similar things about me. When we were married, he had the career of his dreams and was going to college with plans to get his PhD and become a college professor. We got divorced. He seems to have given up on getting a PhD etc. It has been a lot of years. His life seems to be okay. It isn't terrible. But his ability to pursue his dreams seems like it died when his "do nothing" wife with an abusive childhood left the picture. He now cooks for his cute new wife, something he never did for me, and she is in school, but his big dreams seem to have been abandoned.
I am not trying to be mean here. I sincerely hope you get your problems resolved. But I think you are underestimating the work involved in raising kids, running a household and supporting a man's career. I often slept during the day because, unlike him, the kids were waking me up at night.
Best.
