New man withdrawn after parental death

I’ve been seeing a man for two months, we are both in our thirties. A few weeks ago he lost his mother and he seemed fine in the time straight after this. Then around a week ago he went cold on me, i thought we were supposed to meet up at the weekend but he said he’d been in bed all day feeling awful and he needed time to think, rest and sleep. I replied and said I was there if he needed me and have given him this space and haven’t contacted him for about six days. I still haven’t heard from him, what would you do under the circumstances? It’s been over a week since I’ve actually seen him.
