Is this a pre-marriage checklist or one for any relationship?

I sometimes reflect and think, why didn’t I think about THAT before I got married. No regrets, just curious as to why I was actually so clueless.

Help me create a checklist of what somebody should consider during the dating phase so they kinda know what a commitment will really consist of.

Include some examples of things you may have learned the hard way.

Goal: somebody will find this down the road and think we’re all geniuses for helping them be such thoughtful partners.
