So i met this girl while studying for midterms today and at first she was giving me lots of IOIs and it was going well, so I baited her with playing the cube. So we decided to go for lunch with a large group and took 2 cars. At the last second she turns and goes towards the other car where one of her guy friends was there. The other car ended up getting lost and went somewhere else to eat, when we met again by our table I negged her for ditching out and getting lost so I told her to put her number in my phone in case she decides to get lost again so we can meet up at the right spot. She complies and I started gaming her again but she was barely responding to my questions and not re-engaging the conversation, but also she started giving tons of IOIs to her guy friend who was a total AFC and didn't pick up on them.
In the end when we were leaving she asked him if he could give her a ride home and they left together.
This girl is the artsy/hipster type and I would like to know how to game her better. Or should I just find a new target?
