Bruce didn't allow Dick to properly grieve? I would say Bruce picked Dick up and gave him care and stability and understanding while he grieved. Dick has I think himself said that one of the reasons he's so well-adjusted is that Bruce was there to care for him. He didn't want Dick to be like him.
I'd say even in current Bat!Dick incarnations (which are relatively recent) it's not that Bruce is just obsessed with his parents deaths without caring about others, it's more that he has trouble relating to people in a healthy way because he's got issues from that incident and his life afterwards. For all his problems, he's got kids who love him and who he loves.
