I don't know if you have a duty or not, that's really not for me to say. What I will say is: don't think you should care for your father just because you get along well. Think about you growing up instead. Did he take care of you? Brought food to the table? Was a reasonably good father? Being your friend was not viewed as a father's role in many of past generation's fathers, and in many cultures in general. If I had nothing to talk about with my father, I'd still call him sometimes and thank him for having been a good one. After all, he could have just shunned all of it and said "Do I still have a duty to take care of my children, despite me not really wanting this burden?" Of, course, I'm saying this to people who had a distant dad, but one who was at least there, and was at least decent and stuck through it. Your upbringing may have been different.
