How should I handle this?

I’ve been with my partner for almost a year. And our whole relationship he tries anyway to make me jealous...

it never works, I’m not the jealous type, it’s just really annoying !

Especially since he’s sooo insecure I kno if I did half the shit he does and says he’d lose it

I’ve caught him a couple times lying to make me jealous and he completely denies it. Has anyone else went through this? And how should I approach him about it
