What should I do if I see a text message sent by a strange woman on my father's mobile phone?

First of all, you're not sure if your father really cheated. It's just a short message that doesn't mean anything.

Secondly, if your mother finds out, she may go against your father and end up quarreling, or even worse. Perhaps buried in my heart, silent, but a woman's heart is a time bomb, things are not afraid of happening, they are afraid to ponder.

If, your father knows that you told your mother, things will be very unpleasant.

The only way is to write down the message and confront your father. First of all, you should take a stand and never tell your mother. Your father will definitely tell you, maybe it's a lie, whether it's a colleague or a friend. It depends on your own language ability.

No matter what happens, don't do anything stupid to separate your parents.
