Making girls jealous

[chadcel;]

Im dating a girl and going to see another girl who is a friend but likes me and def wanted me to ask her out before.

How do I make her jealous/really into me? Is it enough that the girl Im dating is hot and I show her photos or do I need more info idk.

Can someone explain the female brain pls

Act like you don't give a fuck about her

Won't she just get too offended by me and stop pursuing?

I thought the line of thinking had to be like... Hot girl is completely in love with me, Im meh about her, show friend a bit of attention, she goes crazy thinking about me and how good I must be if a hot girl really likes me that means I must be high value, she pursues me more?
