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.
