Has he got any man mates who could invite him out for a pint or fishing/walking (if he would enjoy that) or football etc... Just give him some time out? Maybe a bloke to bloke approach may help.
I'm not talking about forgetting or anything like that, nothing of the sort but sometimes I find that getting out and noticing how much life there is out there can help me get out of my own head if things are overwhelming, just to get a bit of peace for a while.
As I don't drive, if I need some thinking time I often just get on a bus with my headphones and good music on and just ride around somewhere I don't usually go. Might sound wierd but it often works for me.
Have you got any books on grief and similar? If you had some and maybe left them in places, not too obvious, but where he might pick them up and have a look quietly in his own time? Maybe even leaflets with links to online advice and forums where he can share his thoughts in a more private way - often far less daunting if he isn't keen on talking or seeing a doctor.
Maybe having the knowledge there is somewhere he can go to find support if he needs it and vent or whatever he needs to do may help him in stressful situations.
Maybe a softly softly approach could help him in little ways.
