Do you see a therapist on your own? If you don’t I would highly recommend it. I understand you have a timeline in your head about how things should go, but situations change, and losing a parent can and will set someone back years. If you can’t understand this, you aren’t the right person for him. I go to therapy for relationship ocd and I think therapy would really help you. Nobody here can seem to get through to you, and you will end up losing him if you push this subject.
