lmg, you know what I think about the MC, so I won't repeat it.
Not all men (or women probably) that go through a MLC screw around as part of it, so I wouldn't use that to dismiss the possibility for your H.
I think a lot of the time what people are calling MLC is depression, with perhaps a little of something else thrown in. What you've described of your Hs behaviour sounds like depression to me - lack of interest in sex is one of the symptoms.
You may be able to find a more solution-oriented therapist in your area - there's a section on the DB website, isn't there? I haven't looked, assuming it's all in the States, but since that's where you are, you may find someone that would be more helpful. It's a shame to waste the opportunity, since your H is willing to go.
