wdym you said in #1 that they block you out from the start
now you're talking like they would be already into you, after long interaction
cockblocking is normal - you should expect it and you need learn to deal with
provide more value, and build better connection
if she is really, really into you, the stronger emtion the better, she will ignore friends (however not always)
btw from what kind of girls do you get that response? any ? 10,9,8,7,6,5 ?
"i know what ur trying to do and its not gonna work, go away".
and what is their expression or mood ? are they joyful, smiling or mad, angry, indifferent w8 to for you to get the fuck out of there ?
