I'm an advocate of not asking questions that imbue an aspect of social pressure to do a certain thing or tacitly imply that one's timeline should be hastened.
ie if in a relationship, "when are you getting engaged?"
if engaged, "have you set a date yet"?
if married, "when are you having kids?"
These are plans for the partners to decide on their own timelines...or not if that's their prerogative.
