Anyone else’s SO not get jealous? EVER

My fiance and I have been together 2 years. The fort 6 months of the relationship he was super protective and got jealous heaps and easily.

But then after nearly the 6 month line he just stopped getting jealous.

There was one time I ended up messaging back a guy I used to see , I told my partner about it and he did not get jealous or angry at all?! Just thanked me for telling him, said it was annoying that I did and just as long as I don’t do it again then it’s fine.

Whereas with me I do get jealous, I am a jealous person and if I’m not happy with something i will let him know.

It’s just annoying when he doesn’t get jealous because I’m just thinking is it because he thinks I’m not worthy or good enough to get anyone else ?

It’s just good to see your partner get a bit jealous sometimes because for me it shows he cares and is protective In a way.

Also. I feel like every time someone does message or add me I’ll tell him whereas if the table was turned he wouldn’t tell me ?
