Is he trying to make me jealous?

My bf knows I’m a jealous type. Idk why I’m the way I am.. maybe because I’m a Leo lol (I know zodiac signs are ridiculous but I’m just sayingH anywho, he knows when he mentions girls from the job that he talks to or talks to him, I get upset.. and yet, he keeps bringing them up to me. He’d say something like. “Omg.. this one girl that works on the other side keeps staring at me.” Ect... my thing is, him knowing I get psychotic and angry.. why does he keep telling me , in detail, about what these girls do??? I’m confused?
