Whether two married men and women are having dinner alone is ambiguous or not cannot be generalized. First of all, it depends on when and why they ate together and whether they reported it to their other half.
If two people eat together because it is convenient to talk about work, then such a meal is not ambiguous.
However, if two people eat together during non-working hours, and the reason for eating is purely personal and has nothing to do with work, then in this case, it may be appropriate for two people to weigh whether it is appropriate to eat alone. If you really have an open mind, you should tell the other half about it, not lie to the other half.
Who would believe such a person who clearly ate with the opposite sex but lied to the other half that he was working overtime or talking to a client about work?
Now that we are married, many rules and bottom lines within marriage should be well observed. Especially in the process of getting along with the opposite sex, we should be clear about what to do and what not to do.
Two married men and women, eating alone, are still hiding something, afraid to confess to the other half. In this case, even if the relationship between the two is clear, it will affect the marriage and the relationship between husband and wife. Don't underestimate some obscure and ambiguous relationships. The affair between married men and women is very dangerous, even if it doesn't really cross the line.
