met this girl, we hit it off right away. we've emailed each other back and forth, she asked for my number, i emailed it to her and she hasn't called. it's been a week since. should i move on, or do you think she wants to get chased a bit more? i don't want to quit on her so soon but don't want to be up her bum. i've been going two ways in my head, one she was leading me on, but then she had no reason to ask for my number and have the conversations we had.
