You are doing the right thing.
I was in the psychiatric hospital twice, and it does get harder before it gets better.
FWIW, the group therapy in my psychiatric hospital didn't do anything for me. It's so generic because you have so many people in there with so many different diagnosis'es. It's hard to get much out of a group session when you're in there for severe depression, others are manic, others are borderline, and others are paranoid schizophrenics. It felt to me that it was more to give us something to do and get us out of our rooms and around others than to actually gain any benefit.
I did better when in the evenings I could just hang out in the social room with everyone and watch tv, chit chat, have a snack.
I have to chuckle over one group. They brought this guy in from Emotions Anonymous or Feelings Anonymous - something like that. And he's talking all about his program. Clearly, they are used to people with more of depressive symptoms. And he asked one guy why he seemed so down and the guy told him it was because he was scared because the voices kept telling him that something bad was going to happen to Heather. He was a paranoid schizophrenic. The poor guy from Emotions Anonymous didn't know what to do or say. I felt sorry for him. But, I also had to stop myself from laughing out loud. I mean, seriously, how can you have good group therapy with so many different issues going on?
I was in voluntarily, too. The scariest thing for me was going home. I didn't feel ready. In the psychiatric hospital you're almost cocooned. And the thought of facing reality again when I was still so fragile scared the absolute hell out of me. That may not be the case for everyone, but I wanted to put my experience out there so you're not caught off guard should that be how husband feels.
