All of the replies on the thread where someone asked about if it was a 'test' when a girl says 'i have a boyfriend' seem to suggest that she wouldn't say that if she was attracted to you, and thus the only move is to walk away and find a girl who is attracted.

Why did nobody suggest making her attracted, with pushpull lines for example? Is that a very outdated belief?

I mean, if we accept that the 'I have a boyfriend' line is the point where it's already over, what about girls who say 'i'm not interested', or girl who don't talk back, give very bad body language etc. Are they also example of where no pickup verbals can help?

I'm failing to see the advantage of cold approach over tinder for example, if it really is just about finding the girls who are very very attracted
