After more than a year of separation, my wife sent me a message saying that she wanted a divorce. If I don't handle it, can she go?

Emotional breakdown is not without opportunity to repair, and waste is not the solution to the problem. You can take the initiative to talk to her. You must criticize your questions sincerely and promise to correct them later. After all, the feelings between husband and wife are unforgettable. Since you want to get rid of it, it means that you don't want to get divorced. Your wife won't get divorced unless you have to, so you'd better talk sincerely and save the past.
