I'm a recovering addict and was married to an addict while in recovery. I think through all the losses we had been through together, I only saw him cry twice...and once was for me and the kids.
I wanted to fix him, to help him deal with his "feelings" until it eventually hit me that I was making choices for him. How he should do things, what he should think and feel. As an addict myself, I know how destructive it is when someone tries to do this for me, take my choices away. But, of course, at the time I was wearing my codie hat and wanted to fix him.
I still do this with my loved ones, and have to slap myself on the hand for it.
We all mourn differently, men and woman, from person to person. Maybe you could allow him his way to mourn, even if it is only with silent encouragment.
