I think it's more about the fact that she just met this guy. She has male friends, and I don't have problems with her exchanging her number with a co-worker or people she knows. But a guy comes to you, chats to you, tells you that he's new there and you tell him you going to help meeting people and giving out your number like this? You don't know him, you don't know his intentions, and as a man kinda hurts that my girlfriend wouldn't shut this down before it even becomes something.
