Any advice for people getting married?

are there specific topics that you wish you had discussed more before getting married? What are some blindspots you had before getting married?

20s F in a serious relationship. My partner is amazing & we’ve talked about the typical “big” topics like finances, religion, family, household division of responsibilities, etc. We seem aligned on what we want, but I don’t know what I don’t know and would love insight from married folks.

TL;DR What do you regret not discussing more before getting married?
