I'm kicking into problem solving mode here, hope that's OK. Sorry I haven't read your whole sitch so I don't know if your H is on medication for depression?
If not, I would suggest getting a good quality St John's Wort supplement -- in controlled studies it has been shown to be as effective as ADs for mild to moderate depression and I've personally found it to be helpful. Also I believe that 5-HTP helps, it's an amino acid precursor. You shouldn't take either of those if taking ADs.
Even if he is taking ADs, a good quality fish oil supplement can help too and has been shown to help with depression and mood problems.
I've done all of the above for the past few years and I think it's really helped my moods during a very diffucult time in my life. I'm on ADs now due to my sitch.
A good guide to alternative mood management is the book The Mood Cure. If your H is not open to taking ADs, he might be more open to alternative stuff -- I find that to be commonly the case (even for me).
Hang in there...hugs!
