Hi there… wanna share what I’ve read..hope it helps to make the relationship stronger
One of the biggest mistakes you can make is to try and hide it (in the long term, that doesn't mean you have to display it at the moment you feel it.) Jealousy is usually a signal of something needing fixing, and ignoring that usually only makes things worse.
Instead, I would suggest asking yourself "What do I feel insecure about?" Do I feel unattractive or uninteresting myself? Do I doubt the other persons love for me? Their physical attraction? Do I doubt that I can have the type of relationship I want?
Once you've figured out what the core discomfort is, then it's appropriate to ask yourself if your fears are well-founded. If it is, perhaps talking to your partner about what you are afraid of and why you believe your fears are well-founded makes sense.
In relationships where feelings of jealousy are mild and occasional, it reminds the couple not to take each other for granted. It can encourage couples to appreciate each other and make a conscious effort to make sure the other person feels valued
But when it's intense or irrational, the story is different.
