<human>:  How much younger than you can your girlfriend be without it being weird?
<bot>: In general, there is no specific age difference that is considered “appropriate” by modern standards. The main factors are maturity and mutual levels of emotional and relationship development, not just age. That said, people typically feel most comfortable and confident in relationships that have a similar age range, with a few years or less between the partners. Young adults typically feel more comfortable with partners around the same age, while longer age differences (many years or more) can lead to some difficult issues and differences in values and perspectives. There is no specific age difference which is considered socially inappropriate or “unhealthy”, so you should just choose a partner who is best suited to your age and life stage, and has mutual respect for you as an individual. Keep in mind that relationships are as much about emotional maturity and compatibility as they are about age, so focus on those personal traits while dating.
