I have had not so close relatives pass and there have been no tears. The thing I feel at that point is guilt, for not being sad. When someone very close passed, it was completely different. When I was told it took about 10 minutes before I broke down and cried. That lasted about 20 minutes, then nothing. Cold, numb and just empty. That lasted for a long time. There were intermittent bouts of crying in it. I mostly isolated myself, my wife was ok, but crowds of more than about 5 I couldn't do. The funeral, everyone else was crying and I was cold and blank. Everyone went over to the deceased's family's house and I didn't. The cold and empty feeling lasted for months. I was getting physical symptoms of emotion, but I couldn't actually feel the emotion. It brought on depression and anxiety. I started smoking again, drinking more. Work was barely acceptable, and life just looked terrible. Eventually I moved on, but the PTSD I was diagnosed with remained. It's now been 5 years and it still hurts. It never gets better, but it does get further away.
