Hello pudu: I see this is your first post here on PC. So... welcome to PsychCentral!
I hope you find PC to be of benefit.
I don't know if I can tell you what to do about this.
My wife & I are older people & both retired now. However there were quite a few years where my wife was employed full time & I was not as a result of a combination of physiological & mental health issues. The difference I guess is that, while I spent quite a bit of time on-line (that's a story in-&-of itself), I also did a lot of the cooking, housekeeping & yard maintenence as well as doing basic home remodelling projects. (I also walked our dog twice a day.) So I kept pretty busy.
I can certainly see your dilemma given that your husband supported you when you were struggling but also not wanting to just stand by while he sinks further-&-further into video-gaming oblivion. Unfortunately, in the end, you only have control over yourself & what you do. If your hubby simply isn't motivated to do anything that might help him to heal, there's really nothing I know of you can do to make him want to. At some point you may simply be faced with the decision to either let things remain as they are or to force the issue by drawing the proverbial line in the sand, so to speak.
Here are links to a selection of articles, from PsychCentral's archives, on the subject of how to help someone who is struggling with depression as well as some articles on the subject of helping someone who doesn't want help. Perhaps there will be some suggestions in these articles that can be of some help. This looks like a lot of reading!
But the articles are short. So it's not as much as it may appear:
