What runnerpart said was good advice, don’t stand there waiting for her to re-interact with you, go and open more sets, build some social proof and generally socialise,

But you controlled the set fine, alright it could of gone smoother but your at the very early stage of pick up and you got a kiss and number, that’s a fucking success in my book.

Where you directing all your conversation towards the target? The best way to handle a cock block is to interact with her just as much as you are the target, in some cases more. Win her approval then isolate the target.

Or acquire a wing/teach a friend how to wing and have them entertain the obstacle whilst you seduce the hb with your mad skills.
