Marry with your eyes open. Both pairs.
Weddings get months of planning. Marriages usually get none. The gaps that strain marriages later, money assumptions, family expectations, unspoken life visions, taboo topics, are all discussable now, while goodwill is at its peak and patterns have not hardened. This assessment shows you exactly which conversations you two still need.
Answer honestly as things stand today, not as you hope they will be after the wedding. This works best as a pair: both partners take it separately, then compare reports. Where your answers differ is your engagement's real to-do list, and finding it now is a gift.
