I don't know if this has ever been asked before but i've always wondered it and come across it a few times. is it wrong or bad to act like you think the girl likes you and let her know that you think she does, then continue on and neg her for it?

It is recommended and encouraged to set the frame that she is attracted to you and is hitting on you (her as the sexual aggressor).

It is NOT recommended to "neg" a girl for doing something POSITIVE, because that's returning DISinterest to her INterest. It would be like calling someone an asshole for giving you money. If a girl is clearly giving you IOIs, complimenting you, etc. then RETURN IT with interest by moving closer, touching her more, and flirting with her back!

i would say you can do just about anything so long as it is actually building attraction.

No, many guys out there just act as if everything a girl says or does is an IOI, and hey it works great, especially for those with good inner-game

A quick Layreport where I've done it:

i was gaming a brunette 8with hair all the way down to her waist and things were going pretty well until i got drunk and slept with her friend (who is the Henmother)

now she dumbs me in the LJBF-zone for it, and i act accordingly for a couple of days
then freezes her out for a bit.

me text: hey, i got blown off by my friend, because she wanted to study for a test

her text: aww, that sucks

me text: well her loss, i just rented a movie and got some candy (i.e. chokolade) and tea going over here, why don't you drop by? you were talking about wanting to see inception right? (a status update on her facebook)

her: aww, i so want to see that movie, but i cant right now

me: it's fine just drop by later

her: okay, what time?

me: say 20:00 ?

her: okay

she comes over, and we watch the movie, naturally it gets late, and we're cuddling, i have been kino escalating, and we've been talking about me and her friend (the one i f-closed)

i slow down the conversation, we lock eyes, 1.. 2.. 3.. i go in for the kiss, slowly
she stops me, "no we cant" "i know you want to, you wanted to kiss me all night"
she opens her mouth and put my finger on her lips "shh, kiss me"
she does, we make out, then she stops and storms out of the place...

the next day she shows up, we talk, she reasons i do it again and get all the way.
