What should I do if I find out that my father is cheating?

Let me talk about my opinion below, hoping to help you. First of all, I think your father can trust you to repair your mobile phone, which shows that your father is not worried about you reading those short messages at all ... This proves that the degree of his relationship with this small farmer is at best "playing ambiguous" and there should be no substantive betrayal; On the other hand, as a daughter, seeing her father's ambiguous information, even unintentionally, will bring her a deliberate snooping and distrust, which is not conducive to the father-daughter relationship between you and your father. Therefore, I don't recommend taking a very big "action". Secondly, how to deal with this matter. I think you can talk to your dad sideways, or even make a joke, and bring up the "mistress" of the agricultural workers and see how your dad reacts. If your dad is relaxed and calm, it confirms the previous hypothesis; If your father is nervous and even asks you about your mobile phone, it means that the problem is more serious. In this case, I still don't advise you to make an impulsive move, but calmly discuss with your sister and your mother and analyze how to deal with it (don't make it clear to your father publicly, because men are proud, especially in front of their daughters). If you point it out, he will be embarrassed. I think the key to the problem is to understand it through other channels. It is very important to understand how far your father and the migrant worker "mistress" have developed. If the degree is deep, it will be very unfavorable for you to confront her face to face, and there is almost no way out. In this "worst" situation, you can only talk to your mother and your sister calmly (try not to quarrel, if appropriate, it is best to let your mother and your father talk alone)! In short, I hope you will calmly analyze and think twice before you do! After all, I am also very young (probably not older than your sister) and an outsider, and I don't want to analyze it any more! Remember: you have to tie the bell to solve the bell! Word for word keyboard, good luck! It's late, sleepy, good night!
