If and when they have a disagreement or argument, and if they can’t resolve it, happy couples default to trusting and forgiving rather than distrusting and begrudging.

If you look for things your partner does wrong, you can always find something. 

If you look for what he or she does right, you can always find something, too. It all depends on what you want to look for. 

• Say “I love you” and “Have a good day” every morning. This is a great way to buy some patience and tolerance as each partner sets out each day to battle traffic jams, long lines and other annoyances.
• Say “Good night” every night, regardless of how you feel. It says that what you and your partner have is bigger than any single upsetting incident.

Call your partner at home or at work to see how his or her day is going. This is a great way to adjust expectations so that you’re more in sync when you connect after work.

Happy couples are pleased to be seen together and are often in some kind of affectionate contact. They are not showing off but rather just saying that they belong with each other.
