Families with good marital relationships and happiness often share a simple commonality: they allow each other to be themselves, respect one another, trust each other, and give each other enough space. Love is about allowing the other person to be themselves, not changing them. The most hurtful thing in marriage is controlling under the guise of "for your own good." Many marital breakdowns start with "you need to do it my way." Healthy love is "I love you because you are you," rather than "I love you because you can become what I expect." Trust is the foundation of marriage; without trust, there is no true intimacy. Trust is not naivety, but a choice. Adequate space allows marriage to breathe and keeps love fresh. This space gives both partners the opportunity to maintain their individuality, develop personal interests, and sustain social circles. With such space, couples can share new experiences and have independent insights to communicate, rather than being trapped in the monotony of daily trivialities. Mutual respect is the secret to a lasting marriage; respect is reflected in all aspects of life, respecting each other's choices, feelings, and even small flaws. The most hurtful things in marriage are often not the big storms, but the accumulated disrespect over time. Respect is the bottom line of love; love without respect is merely control and possession. True respect means that even if I do not agree with your choices, I defend your right to choose; even if we have differences, I acknowledge the validity of your viewpoint; even if you fail, I won’t kick you when you’re down, but will face it together with you. Marriage is not 1+1=2, but 0.5+0.5=1.
