One thing i noticed recently is that i will often go with b AS A BLUFF. That usually gets them to show an obvious IOI or IOD. Especially if you get into talking about your relationship.
For ex... "i dont get u HB. You seem like a cool friend but you dont ever have time to hang (or whatever) Ur confusing lol (and thx to RB for this line).
Hb:' well thats just me blah blah'
Pua "well maybe i was wrong about us being good friends"
Hb" ok. Goodbye! (Or something equally confrontational)
Pua (smiling, stroking her hair)' be careful what u wish for. Because if u want me to leave, i am not coming back.'
Then leave. Most times i start walking and they either say just kidding and stop u. Or they will text u after Freeze Out for a few days. But keep in mind THIS IS GO FOR BROKE. You can bluff it but you must be prepared to leave forever.
Another way to do it is if she turns it around calls u confusing, tell her to say she hates u (flash a cheeky smile). She may not be able to... or she may say it. If she does say it, tell her her eyes give away that she's lying.
