Here are some aspects that can affect how the age difference is perceived in a couple:
Life experience and moment of life: People of different ages can have different levels of life experience and be in different phases of life. This can create difficulties in understanding and cooperation, especially if the partners have different goals and plans for the future.

Cultural and social expectations: Age differences can lead to differences in cultural and social expectations. This can become a source of conflict if the partners cannot find a compromise or do not understand or accept each other.

Emotional Maturity: People of different ages can have different levels of emotional maturity. This can affect their ability to understand and respond to each other's emotional needs.

Stigmatization: In some cases, society can stigmatize couples with a significant age difference, which can lead to social pressure or feelings of rejection.

Although the age difference can be a factor that is difficult to overcome for some couples, it is not always an obstacle to a happy and stable relationship. The main thing is that both partners have mutual respect, understanding and are ready to work on building a healthy and satisfactory relationship.
