He won’t fully recover this version, but maybe CA will help him one day. If he’s not abusive you are quite a special person to stick it out. I don’t drink a drop. But I do have severe chronic depression and anxiety, and my IRL husband has faithfully stuck through its ups and downs for 19 years and if I know anything I know that I am totally utterly completely eternally loved. It’s the most amazing feeling and he is the most amazing husband ever!
Now Stardew is fantasy and not reality, but your Stardew husband is sick and not horrible. He’s not abusive, just improperly medicating. He is going to and through counseling, just hasn’t made full recovery. He’s sick. If your strong and don’t have true iRL struggles that already need iRL energy and strength then keep with him. I have on other saves. You will see a few good lines mixed in with the mostly neutral or depressing ones. There are mods that help him have a better outcome, and who knows the next update might help. CA said there would be more dialogue lines somewhere here. Never know. I can’t change dialogue lines in a game, but there’s always much hope for the mentally ill and suffering iRL. Best wishes.
