After the Divorce, the Richest Man's Ex-Husband Pursued Him Crazily

The author will not let the heroine go even if she is reborn, and arranges for the heroine to be with her husband who was indifferent to the heroine's death in her previous life. There is also a title: the heroine was not divorced before her death in her previous life, and she was not divorced after her rebirth. Where did she get her ex-husband? I have never been divorced. Where did the title of the book come from? It's hard to describe in one word!
