OP, people aren’t trying to be difficult or judge your relationship. The questions people are asking have important answers. The age difference matters, not just how wide a gap, but at what ages you two personally are. For example, a 20-year age gap may mean totally different things in different offices. In a country where male younger than female relationships are locally uncommon, COs are much more harsh about age gaps, particularly if the female is older than child rearing age and the male has no children. Similarly, the amounts of money sent, and in what manner (a large lump at the start of a relationship, full maintenance, or occasional gifts/expenses) matter enormously. “Face time” also matters enormously. If you aren’t willing to answer those questions with specificity it becomes extremely hard to give you informed answers about your specific situation, all we can give are generalist answers.
