Did I screw up my chances with this girl?

She gave you her email dude. You now have some sort of contact with her. So no you didn't fuck it up. Unless she was like hesitant about giving you her email, then you might have an issue. But you probably should have asked for her number. Just remember, girls like a man who is confident in themselves. That doesn't mean be conceited and brag about yourself. Just show her that you're a confident good guy. Oh and don't be too smothering. Girls want some kind of challenge, so don't email (or text) her all the time. Just say hi with a warming smile every once in a while when she walks into class or if you see her in the hallway. That'll get her thinking. Good luck mate! Hope all goes well!
