No, it is not common for men (or women) to forget their spouse's name after getting married. Forgetting a spouse's name would be considered unusual and might indicate a larger memory or cognitive issue.
Marriage is a significant event in a person's life, and their spouse's name is typically something that is regularly used and remembered. In most cases, people remember the names of their loved ones, including their spouse, throughout their lives.
Occasional forgetfulness can happen to anyone, but it's essential to differentiate between normal lapses in memory and more serious memory issues that might require medical attention. If someone is experiencing frequent forgetfulness or memory problems, it's best to consult a healthcare professional to identify any underlying causes and receive appropriate advice or treatment.
