Never go to bed mad. You can't fight while holding hands. Speak softly; shouting escalates anger. Choose your battles carefully; very few things are really worth fighting over. A happy marriage is the hardest job you will ever have; give it 110% for 100% of the time. DH and I have been married 42 years; my parents were married 75 years; his parents married 46 years (until DFs passed). Good wishes, and congratulations on Wanting marriage to be a success.
