2. Give each other a kiss before bed at night; if you argue one day, this habit can keep you from falling asleep.
3. Blow dry each other's hair.
4. Don't be easily brainwashed. Avoid reading articles like "Arguments can strengthen relationships," "Guys apologize first during fights, that shows you love her," or "No expensive gifts means no love." Growing together as a couple is the key; others' relationship formulas may not suit you both.
