Instructions
Slap your wife, attack her, laugh at her and basically be as mean as possible toward her and your divorce will be granted in no time.
Ignore your wife. Abstain from giving any kind of intimacy or gifts, and do not check in on her. Do this for several days and it is almost a guarantee that she will leave you.
Do not give your wife a budget. This will make her very upset, to the point of resenting you. She will become miserable and make her way out of the home and out of your life for good.
Kill your wife to be granted freedom from the marriage. This might be immoral, even for a video game character, and you will get evil points, but if you want the divorce for sure, take her to a place that is remote and do the dirty deed.
