As long as you're 18+, it doesn't matter. Below then, it's best to follow the rules of the state you live in (age of consent, for example).
In Florida, the "four-year age difference" rule typically refers to the state's laws regarding sexual consent and relationships involving minors. Florida law allows individuals aged 24 or younger to engage in consensual sexual activity with individuals who are at least 16 years old, as long as the age difference does not exceed four years. This means that while there is some flexibility for younger individuals, it is important to be aware of the specific legal age of consent and the implications of any age difference in relationships.
Any adult relationship can work regardless of the age difference provided the two involved are committed to each other and do the work to develop their relationship.
Age is not particularly the problem in relationships, i think it rather depends on the maturaity level of the two people trying to establish it.
If you are both are consenting adults then no, a 13 year difference in age is acceptable. However, the relationship would be far more successful if the 13 year difference began at 25 years of age or more with a partner who is 13 years older. If the 13 year difference in age is with too young a person the relationships seldom work out because of maturity problems.
age doesn't matters, if you are desperate to marry each other.
it is neither wrong nor uncommen. many relationships have an age difference
The law is mainly interested in age differences when one person is below the age of consent. The age of consent varies depending on where you are, and sometimes what gender you are. Generally speaking if both people are above the age of consent and not closely related to each other, there are no legal issues with their conducting a romantic relationship. Romantic relationships involving differences in age are relatively common. Sometimes men and women are involved with people who are 20 or more years in age difference between them. Just because there are no legal impediments doesn't mean that everyone would approve of a large difference in ages. In some cases (for example teacher-student relationships) it may be considered illegal or unethical to maintain a relationship.
Relationships between people in high school of different ages are very common. They happen because age no longer matters as much in high school as it does in middle school.These kinds of relationships may be different in the sense that the older person of the couple is able to drive, allowing the couple to go out way more.
The age difference between Bill Wyman (then Rolling Stone) and Mandy Smith was 34 years. He was 47 and she 13 when they first started dating with her mother's permission. The press coverage of this and their subsequent marriage 5 years later supports the view that the Press thought this was a significant difference in age for a relationship. Their marriage only lasted two years, allegedly due to Mandy's poor health.
No in fact Abraham and Sarai were ten years apart. More than likely, Ruth and Boaz were much farther apart in age than that, so age difference is not an issue. It does however put a premium on family, espescially parental, approval. It was unthinkable for a couple to marry in biblical times without approval of both families.
