Just Do It! (As a famous apparel seller used to urge us.)
Once you start threatening divorce, you start to weaken the bonds of marriage.
Some people, who want to remain married, threaten to divorce their spouse to get the spouse to change some behavior — stay home more, quit drinking, pay attention, etc.
What the other spouse focuses on, though, is that the first spouse wants a divorce. This feeling becomes stronger as the threat is repeated over time.
If you want a divorce, go ahead and file, or discuss it if you want.
If you really want something else, skip the attempted pressure tactics and have a discussion about what can be done to improve a problem area. Threatening divorce will not solve the problem and will probably result in divorce.
