Whatever the case may be, money is a major source of conflict in most marriages. The key issue in the majority of cases is financial hardship. When you have less money and more costs, you might run into major problems. Many marriages fail in most developing nations as a result of this issue. In certain circumstances, having more money is an issue. For example, if one spouse makes much more than the other, there can be a problem with inequality. In most countries, economic hardship is the number one cause of divorce. This is true not only in America, but in Europe as well. According to research, unemployment rates are high across the globe. This means that many people are unable to meet their financial obligations, which can lead to divorce. In addition to poverty, other issues such as violence, addiction, and mental illness can cause marriages to fail. Some couples find it difficult to stay together when one of them is suffering from cancer or some other disease. If one spouse is physically abusing another, they might be able to keep their marriage together during times when there is no physical injury, but eventually suffer psychological damage. This can lead to divorce later on. Finally, some marriages simply fail because of differences in opinion. No matter how much you love someone, if you don't agree on some things then the marriage will not work. For example, one person might like to go out dancing every night while the other wants to stay at home all day every day.
