I think its important to "be there" for your husband, but in a lovingly detached way. Don't expect him to come to you, but be willing to just listen if he does, then validate.
Death can be a pivotal breaking point, either life is too short and its time to move on, or life is too short what am I doing to wreck it. Be ready for either, or both at certain times in the near future. The roller coaster might have some all new highs and lows for the next couple/few weeks.
Hope your doing well, stay strong, keep on keeping on.
