Artificially inducing jealousy in your significant other is a fairly popular psychological technique.
It is generally accepted that the person towards whom this technique is applied begins to appreciate his partner.
At first glance, yes. Let's imagine a situation: a guy doesn't care much about his girlfriend, rarely gives her gifts and almost never invites her to restaurants.
It would seem that in this situation, it is enough for a representative of the fair sex to start flirting with someone else. As a result, the man will understand that his other half is in demand, and will begin to save the relationship: he will become more caring and generous.
But it's not that simple. It turns out that inducing jealousy is a very dangerous technique that can lead to a breakup.
A person using this technique is probably counting on renewed interest from their significant other.
In fact, in most cases the opposite effect is achieved: the one who was made jealous becomes disappointed in the partner.
Don't think that a guy whose girlfriend has started flirting with someone else will think like this: "It turns out that many men like her. So I need to take her out to restaurants more often and give her expensive gifts. That's the only way I can keep her."
Most likely, the guy will come to the following conclusion: "Does she really love me? If she behaves like this in front of me, then what will happen next? I can hardly trust her!"
Thus, artificially causing jealousy in a partner is not a saving technique, but a destructive one for relationships. Do not use it under any circumstances!
