i realise this might be too personal, but i'd be interested in knowing what you thought was useful after all that time (i've been in a relationship for around 15 years).
Styles of talking while discussing problems. EVERY marriage has problems, for sure, but how a couple deals with problems can make problems part of what enriches the relationship, or part of what drags it down. We encountered some new kinds of problems in the last few years (from the outside), and thus had this interest recently.
