How do I connect with a girl again?

Yes well if you like her don't screw around playing games like puposely not beeping her. Just pop in even if your in a hurry and say wanted to say hi how was your day be thoughtful she'll appreciate that then if you have to go at least you made contact. It doesn't sound like you were bothering her earlier so your still okay to chat. specially if your getting along. Its never nice to play games anyways be yourself.
