Getting divorced is much more complicated and time-consuming than getting married, and may require property division that you did not expect or protect against. Business owners are often particularly vulnerable in divorce because a business may count as marital property. Without careful planning and willingness to make sacrifices, a business owner's divorce can end the marriage as well as the business.
All married couples go through struggles, both due to external factors and due to issues within the marriage. It could be said that the way these issues are handled is the key to whether a marriage will be successful. You can only control the way you handle the situation, and you may feel frustrated by your spouse's lack of effort and support.
It is common for people to stop worrying themselves about the behavior of their spouses once they make their minds up to seek a divorce. After all, you won't be accountable for their decisions for much longer. However, that sort of dismissive attitude could end up costing you some of your financial liquidity in the future.
