My H didn't want to talk either - but then I'm not much help, since he still doesn't want to talk
Why not give us some idea how you are approaching him - these guys are pretty good at giving advice. But it often is a matter of just keeping at it (and finding a way to do that that doesn't seem attacking). Find a loving way of letting him know you're serious.
Why not ask him when would be a good time to talk. Let him know you're serious about working on this together - make sure he understands that you're not blaming him but trying to find a solution. You can't force him to talk, really all you can do is let him know how serious this is to you, and hope that he cares enough to take you up on it. If he does care, and you provide a 'safe' setting for him to talk (he doesn't feel attacked or ashamed) then he will open up eventually.
It may be that you two have to 'practice' intimacy again (I have to admit, I don't really remember your sitch) so it might be a good idea to 'talk' about other, less difficult topics first, to help him understand you're on his side.
