Marriages often struggle because of a lack of communication, mutual goals, and intimacy. Financial stress, unrealistic expectations, and constant arguing are other top causes of divorce, yet sometimes these difficulties can be worked on to save the marriage before it is too late. In other circumstances, the marriage may be beyond repair. One study showed that the most common major contributors to divorce were lack of commitment, infidelity, and conflict or arguing, while the most common reasons for being the “final straw” were infidelity, domestic violence, and substance use.
