So there's this guy who my girlfriend knew a year ago. He sent a message to my girlfriend that he wants to meet her 5pm today. I was not furious about this until she told me he was flooding messages. Well, as a protective (or you could say overly attached) boyfriend as I am, I thought that, hey, that was beyond her privacy. I think you got the idea that she does not want to see you.
Guys should know boundaries. When girls refuse, don't flood them with pleases. I mean, that's not how you get girls. You have to wait for the proper timing to meet them. And knowing she has a boyfriend, that was not the proper timing. Yes, for you, that would just be a friendly meeting. But for the girl, and most probably for his boyfriend, it might mean something else. ;)
