I want a divorce, but my wife doesn't agree. I don't know how to persuade her.

Let the two sides separate for a while and think about it. Maybe time will change the status quo. Maybe your marriage will become stronger because of the temporary separation. Maybe through a separation, she will figure it out; Even if you don't figure it out and divorce resolutely, you can separate for two consecutive years because of emotional discord and go to court to sue for divorce. It is best to strive for good communication.
