What should I do if I find some ambiguous messages in my father's mobile phone?

That person may love your father silently, but your father already has a wife and children. It is immoral for her to do that, but she can only say that she is wrong and can't assert that it is your father's fault. You don't know what your father is thinking now. You need a suitable time, such as when mom is away and dad is in a good mood, talk to dad. You can recall the warm moments at home with your father first. Think ahead and tell your father truly and vividly. After all, you are his child, and besides, at your age, he will listen to you. In addition, you can also use your imagination and look forward to a bright future at home, so that dad can see that he has an excellent child and a warm and happy family. These details of life seem ordinary, but they are still very popular with dad. I wish you happiness!
