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.
