19. Make sure you agree on the big stuff
Do you want kids, how many?
Who is going to be a stay at home parent if any?
If we both get the job of our dreams and both require moving, what do we do?
What is okay in case of unplanned pregnancy?
How should our money be set up and spent?
Is religious belief important? If so what religion? What if one of us changes/gains/loses religion?
20. Have separate blankets. Nothing builds resentment like a freezing butt at 3am.
21. Admit when you’re wrong. Ask open-ended questions when you’re right.
