If a spouse has a problem with how their mate interacts

Tweet

...does the spouse have the right to dictate how their mate SHOULD interact with said other person? Keep in mind, the spouse has acknowledged that the behavior of their mate is innocuous and not inappropriate, and has also admitted that the "problem" is irrational and baseless. If the spouse is the one with the problem and, by their own admission, their mate isn't doing anything wrong, isn't it up to the SPOUSE to work through the problem? Should the spouse NOT make it the problem of their mate (who shouldn't have to stop doing something acceptable just to placate the unreasonably threatened sensibilities of their spouse)?
