If we consider it from the perspective of morality and ethics, it is definitely not good. We're all adults. No one will be nice to another person for no reason. He always drives you to play. If you go there more often, you must know what he wants. If you really become his mistress, then you are the third party. If something happens to the public, it is you who destroys other people's families. Besides, how many mistresses can really take the lead? Even if it is superior, how long will it take, and then your children will know what they used to think. Therefore, it is better to find an honest man, take normal steps, fall in love and get married, and finally live a stable and happy life.
