sorry if you got any bullshit reply from a newbie. We just have to tolerate them

here is the answer
being persistent means not letting the girls behaviour affect you and keep gaming in a non-needy way. If you are going to be persistent with a girl then your motto should be, "i am not going to stop gaming untill be clearly says me to fuck off or not to contact her"
some girls have this kind of thing in their head,"i am not going to sleep with a guy so quick. It woud mean i am a slut." and these girls would make you wait a certain amount of time even if they like you, even if they want to bang you in five minutes. With these kinds of girls you need to be persistent. As they reach their peceived time limit they would let you make advances. Byetheway these types of girls prove to be good gf material.
