Well, it's very simple!
You used to be together and when you were together you developed a natural desire to protect your relationship.
Jealousy is simply the expression of that desire to protect your relationship.
Whenever another girl would come closer to your boyfriend, you would wake up this emotional reaction which would sound like:
"It's with me he is. Stay away from him!"
Yes! This is jealousy!
Ans there is nothing wrong with expressing small dozes of it in your relationship as long as you don't become a slave of it.
Now, what happens when you break up?
You end a relationship but some of the emotional reactions associated with your ex stay in your mind.
You might feel desire for him, slightly possessive, or even imagine your future with him even though you rationally know that you are no longer together.
To stop the jealousy pattern, you need to consciously reprogram your mind and develop a new set of emotions when you are around him.
This whole process + the strategies to create that shift are described in detail in the e-book and MP3 audios available at:
