Deadbeat husband

I have been so close to divorcing my husband many times.

He has sociopathic traits, which means no emotions or empathy and a lot more problems. He works one day a week. He doesn’t do chorse, clean up after himself, chores, or run errands. He has no social life. If I ask him to do one thing, he will spend all day on it. I am basically babysitting him 24/7. He goes where I go. We have one car so I’m usually stuck driving with him. He has no goals or hopes or dreams. He has myriad social and mental issues.

I’m a full-time medical student working part time and responsible for doing chores, cleaning, making calls, being his counselor, etc. all at the same time. I’m burned out. I have no social life anymore and no friends. He is dragging me down with him. I feel like I am unable to live a normal life anymore. His idea of “normal” is completely abnormal. I need help. Any suggestions? We just started therapy and that’s why I’m holding off on leaving right now. I’m so depressed.
