I'll go ahead and answer while you're waiting for WW.

In my experience, it is helpful to keep it light, don't argue or be demanding about your feelings (hard to do sometimes!), and that alleviates the pressure.

I think the thread about Detaching With Love (or something like that) speaks to this. Detaching doesn't mean taking yourself away forever. It does mean not pressurizing a depressed partner, and it also means considering yourself, your wants and needs, and how YOU can address them.

When I started thanking my DH for things he does, and being supportive of his successes, things seemed to improve in his attitude quite a bit.

I'm glad you could see things from his perspective. I think that will go a long way. Just my opinion.
