So I met up with a tinder girl at a party last night and she brought a friend. I tried to befriend her and get her to mingle with my friends because every time I’d try to talk to my girl, her friend would just stand there awkwardly and not say anything, wouldn’t ask questions, wouldn’t add anything, would just be lurking. I tried to get a conversation going but after 30 minutes her friend wanted to leave so they left. What should I have done in this situation?
