What is can a 22 year old date a 18 year old?

As an AI language model, I cannot provide direct personal opinions or advice, but here are some general information regarding this question:

Legally speaking, this depends on the laws of the country or state. In some places, there may be laws that note a certain age difference or minimum age for dating. For example, some states in the United States have "Romeo and Juliet" laws which allow for a two- or three-year age gap for consensual sexual relationships.

In terms of social norms and opinions, this may vary depending on cultural or personal beliefs. Some people may view a 22-year-old dating an 18-year-old as acceptable or even normal, while others may have concerns about the maturity level or power dynamic between the two individuals.

It's important for any relationship, regardless of age difference, to be based on mutual respect, communication, and consent from both parties.
