Jealousy portrays that someone is afraid of losing the other person but when jealousy reaches unhealthy boundaries, it becomes insecurity and that can account for a lot of breakups. Jealousy in a relationship comes out almost naturally but here is how you can tackle the issue before it damages your relationship or make things worse for you.
Give them assurance.
Jealousy in a relationship is inevitable and the moment it comes out, the first thing you need to do is that you need to give them assurance. Yes, you need to remind them that you are never going to leave them and that the other person isn’t as important as they are. Listen to them and don’t begin to label them as insecure. Hear them out and make them feel better.
