In modern society, cohabitation has become a very common phenomenon. It seems that people's definition of love has become very vague. If they are together, they will be together, and if they are not, they will be separated. There is less attachment and more letting go. Maybe it's because people's awareness of self-protection is getting stronger and stronger. If you love deeply, you will be hurt, and you won't open your heart easily or make a commitment easily. Therefore, cohabitation appears. Living together does not require any responsibilities. When love disappears, you can just pack up and leave without dividing any property or worrying about any disputes. But is this really good?
