Hello Sd: Thank you for bringing your concern here to PC.

I see this is your first post. So... welcome to Psych Central.

One additional forum, here on PC, that may be of interest to you would be the partners of people & caregivers forum. Here's a link to that one:

The short answer to your concern, from my perspective, is that it is reasonable for your spouse to expect you to listen for a
reasonable period of time. But hours a day is not a reasonable amount of time. It sounds to me as though your spouse is using you as a substitute for the professional mental health services he needs but is not pursuing. To my mind, this becomes a matter of personal boundaries. Here are links to 6 articles, from Psych Central's archives that discuss the issue of personal boundaries within relationships:
