We can't diagnose people here. And it seems your husband is all over the map. It sounds to me that that your husband has some issues with being immature and irresponsible. He's already setting himself up to get away with not having a job by saying "oh i don't think I can keep a job" He is a big kid. Staying up late, not wanting to get up in the morning. As for chores. It's not an "if you need help" kind of situation. He has a responsiblity to do them.

Trying sitting down with him and working out a sharing of chores. He has his and he does them without you asking.

Sometimes we can fall into a situation of enabling loved ones by taking over more and more responsibility for them. It's a dangerous trap to fall into.

If he truely has some kind of disorder he needs to get medically evaluated. Again that is his responsibility to do that. Even when we are mentally ill we need to be responsible for our own actions. Best of luck to you.
