"人々が結婚を続けるのは、望んでいるからであり、扉が閉ざされているからではない。"

Simplified Meaning:

People who stay married choose to do so because they love each other and want to be together. If someone feels trapped or forced to stay in a marriage, that relationship won't be happy. Think of it like a job you love and a job you hate. In the job you love, you stay because you enjoy the work and the environment. If you hate your job, you might only stay because you need the money, but you'll be unhappy and stressed. In a marriage, it's similar. When people stay together by choice, they invest time and effort to make the relationship fulfilling and joyful. They are like partners working together, supporting each other through good times and bad. If someone treats their marriage like a job they love, they'll work hard to keep it strong and healthy. Just as with any other commitment in life, choosing to be there makes a big difference in how you feel and act. When people in a marriage feel free and valued, they are more likely to stay committed and happy, leading to a more successful and loving relationship.
