Yesterday while running a game on a girl ( maybe I have done the kino escalation too fast xD) I hugged her i tried to kiss her. She immediatly retreated in a defensive position with her arms crossed while in the hug. She blocked me after giving me several ioi s. Do you think this is a buyers remorse? How could i retook her to a comfort state? by negging her?

looks like ur using a lot of the lingo to fit in. No first of all u hugged .Thats enough. the kiss is too early on. u could pull it off if u had really good body language and congreuncy but that takes a lot of practice. If she pulls off u do the same dont take it personally just laugh it off and divert the topic.
DUDE NO this isnt buyers remorse.buyers remorse is when u bang a hb 10 only to find out she bad at talking. its some thing where u invested a lot of time only to find its not worth it which in your case it isnt.
u can try to neg her. but understand that negs are for clubs where the hb's are defensive. in most of my approaches (ie daygame) negging seldom works. DONT neg ull make it worse. just sarry on from where u left off ie. more kino, hugs, high fives, only kiss when ur absolutle certain theres IOI's

look for dilated pupils
closed relaxed shoulders
a small o shape forming between their lips at the centre

Thank you for your advices... The next time I will experiment kino escalation to find out if it really works and try to bypass these awkard moments xP ( she also lyed that she has a bf... )
