My spouse is always wanting me to help him with something, his work, his school, getting things for him, etc. He diminishes what I do for others or the work I do around the house. My parents live with us and both are very sick. I have help seven days a week. If what I do for my parents interferes, or even if it doesn't, with what he wants me to do for him, he gets angry and says very hurtful things about them. Our relationship has never been great. I just don't like him saying things about them. He has no heart. He only thinks about what he wants. I really dont like doing most of the things he asks me to do because they take a lot of time and are usually annoying. For example, he has started an online course for an advanced degree program and can't figure things out so he enlists me to read the syllabus and figure out the assignments. In the meantime I have other pressing things to do, but he thinks those things are unimportant compared with his stuff. He is 70. If I could l would like to get a divorce but I have my sick parents to think about. Saying no to his requests always leads to arguments. What can I do?
