Dude, why are you going on a forum to speak about this girl you've only known for a few weeks. She's probably scared cause you're coming on too strong. I think the fact that you came on this forum to speak about it rather than going to friends shows that you are a bit too keen (my personal opinion) and that might show in your messages to her. Maybe lay off her for a bit and let her come to you. If she doesn't then at least you know that she wasn't that interested. Play it cool bruh.
