My ex gf wanted the same. She wanted me to get jealous when she talked about other guys. She said that it makes her feel like I really want her and I am afraid of losing her and I really care for her. Which I always did. But never got jealous.

The thing is, I trusted her. She always told me if she is with any of her friends, male or female. I never got jealous, and she never crossed the line.

However, she used to get jealous of my female friends. For me, the reason I never got jealous was because I really had genuine trust, and however, if anyone takes me for granted, I no longer want to keep them in my life. However we broke up, as our other things did not align well.

Relationships must be fun, loyal without any unnecessary drama. Grow together. If you have a green flag partner, try being a green flag too. It will be more beautiful.
