We have a number of questions regarding dealing with jealous people. From a search I found 7 open / 2 currently closed candidates:
How can I tell my wife that her fears and mistrust are hurting us?
How can I convince my partner to accept my best friend instead of wanting to break up?
Is it possible for my friend to resume communication with his unofficial sister without earning her husband's mistrust?
Girlfriend's sister's boyfriend talking excessively to my girlfriend
(closed) Is it unreasonable to feel uncomfortable when my Girlfriend frequently talks to her ex?
(closed) How can I go out to lunch with a friend's partner with him not feeling betrayed?
Would it be appropriate to make a new tag, jealousy and add it to these questions?
According to the help center:
A tag is a word or phrase that describes the topic of the question. Tags are a means of connecting experts with questions they will be able to answer by sorting questions into specific, well-defined categories.
As an example this would be like the existing tag anger,
To be used when question you are asking is dealing with anger of yours (in interpersonal context) or someone/something else.
So I think this would fit in with our current tagging schema, but I wanted to get meta input first before bumping all of these to the front page :)
