A blogger from Scientific America came up with an empirically supported marriage, and made the following recommendations:
#1: On a daily basis, think about what your spouse does that you value, and verbally express your gratitude.
#2: Everyone fights occasionally, and what determines whether couples stay together isn’t whether they fight, but rather how they fight. When disagreements arise, listen to your partner, acknowledge the role you had in the conflict, focus on specific behaviors rather than criticizing your partner’s personality, and share concerns in a polite, empathetic manner. Respect each other in good times and bad.
#3: Exciting activities that increase your heart rate will let you benefit from misattribution of arousal. So for the sake of your relationship continue traveling, exploring, mud-running, moving cross-country, and taking risks — as a team.
#4: Although it’s good to do things together, it’s also important to support each other’s personal freedom and autonomy. Help your partner continue to be that individual by respecting their personal goals and interests.
