15. Always answer the phone.
One rule I’ve followed for the last decade is that I never ignore calls from my wife. If she’s calling or texting me, I answer no matter what.
16. Never go to bed angry.
Remember that the last words you have spoken to her may be the last words she ever hears from you.
17. Respect and more respect.
Respectfulness is often more important than the old saying about communication. Respecting your partner, being mindful of things they’re doing, etc.
Learn when your partner is focused on something, and avoid interrupting them, etc. Respect each other’s need for free-time away from each other.
Respect your partner enough to not trash the house, or force your partner to do all the household chores.
