In many readings and theoretical discussion concerning game and attraction - jealousy plays an important role in making women lust for you. One question I have is, lets say your plate/LTR sees you flirting/chatting up a girl who is presumably not as good looking as her. But she sees that you are smiling, laughing and enjoying yourself. Would this incite a reaction of jealously or would she not care in that she knows her overall looks are much higher than this other female.

TLDR: Would a plate or LTR be jealous if she sees you talking to another girl who isn't as good looking as her?

Also, are all women just really insecure and would this cause dread no matter what the other girl looks like??

Thanks
