You poured your heart and soul into your company. You have every reason to want to protect it. Most people who start their own businesses invest significant amounts of their own time and money into making something financially successful. All of that investment can pay off with enough hard work, allowing you to support yourself and your family with the business you created.
If the thought of divorce is inspiring fear, you are not alone. In general, society places a stigma on divorce and a higher value on people who remain married. This creates a lot of pressure to stay in an unhealthy marriage. However, divorce is stressful enough without these societal pressures. It can change your life in completely unknown and unexpected ways.
