My parents' relationship has never been very good, and I haven't said a word when I got home.

In fact, children should not care too much about adults. If you are a girl, maybe you can talk to your mother, ask her what she thinks, or tell her what you think.

I don't know if your parents are young, so I'm just saying what I think, and I'm not sure if it fits your situation.

Many times, in a family, parents will choose to continue to make do, without feelings, because this is a complete family. And if your father and mother are separated, your father may have an affair like you said, so he may find a new life more easily. But what about your mother? If you are really separated, have you ever thought about what your mother can do in the future? What about you? Who do you live with? In addition, if you really separate, there will actually be some differences that you may not have thought of for the time being. First of all, your mom and dad shouldn't live under the same roof. In addition, for example, your parents will not be separated during the Chinese New Year, and your mother will be at your father's house (also your mother and your house) during the Chinese New Year. But if you are separated, your mother will not be your father's daughter-in-law, and it may not be suitable for the New Year. It's hard to be confused. If you care about your mother, listen to her, study hard and be filial to her when you grow up.
