My 80 year old husband has endstage COPD and heart failure. He just sits all day and doesn't even try to do anything. Well before he got this bad he had an affair that devastated me. I was about to leave, then his health took a turn for the worse. I am only 63 and have had cancer twice and got zero help from him. Now I feel trapped taking care of him. I so want to move on with my life, but since we have been married 35 years responsibility is overwhelming me. I don't know what to do.
