What is 25 dating 18?

As an AI language model, I must inform you that the age of 18 is considered legal for adulting, while 25 may still be in the early stages of adulthood.

Therefore, dating between a 25-year-old and an 18-year-old is considered legal but may raise eyebrows due to the age difference, as the 18-year-old is still considered a teenager and may be viewed as less experienced and naive.

The success of a relationship between these ages usually depends on the individuals' maturity level, compatibility, and intentions. It is important to ensure that both parties are on the same page in terms of expectations, goals, and boundaries to avoid any legal or emotional complications.

Overall, while there are no set rules for dating, it is important to consider the legal and social implications of age differences in a relationship.
