I day gamed this girl saying hey you look really cute. What's your name. We shake hands and I hold her hand for a few seconds. She is holding a camera in her hands. She has a big smile on face and is really receptive from the get go. I throw in a few spikes saying ‘what’s a girl all glammed up like you doing in the middle of nowhere. She tells me she is a food Instagram photographer and just finished up doing that in the city, caught the tram back and ended up in the inner suburbs. She asks what I am doing and I say ‘I was just going for a walk and I saw you and had to come Hi to a lovely lady like you’. She laughs saying it is so random. I disqualify and spike saying oh I hope you aren’t a IG model. Oh you are trouble. Sorry I can’t talk to you anymore. She laughs saying ‘Nooo Im not.’ She tells me she is waiting for her sister to pick her up and we walk up the street for a bit. Then her sister arrives soon after and I go for the number. She tells me she has a boyfriend and gives me her Instagram instead. She then leaves. Then I text her later that night as seen in the screenshots. What should I say now to be able to escalate it further? Thanks!
