There is an interesting sentence. If you want to see a person clearly, let's travel together.
Traveling together means eating and living together, and then a person's nature is exposed. From the bits and pieces of daily life, we can clearly see a person's nature, good and bad will be fully revealed.
Therefore, after living together, you will obviously see some very bad personal habits of your girlfriends, and then there will be many small dissatisfaction and even contradictions that cannot be ignored. For example, you are too lazy to clean up, or your clothes are littered.
In addition, cohabitation means that privacy is difficult to protect. Some people are naturally curious about this and that, and their mouths are unreliable and prone to conflicts. In addition, in case their friends or even partners visit, the other party will be embarrassed and so on.
