Hey i have been talking to this girl for about 2 weeks. The first week we would message each other like 3-4 times a day, i know a little excessive. She was also on spring break the first week, and has since returned to school this week. She gave me her number and we texted a little on Mon and she told me to call her on wed. So I did but she didn't return my call, no big deal. She then texted me the next day and apologized that she didn't return my call. She said she is really busy with school work. However here is my question, should I go back to emailing her, so she can answer me whenever or wait till she calls me, whenever she has time? I don't want to be to needy but i don't want to just stop talking to her either.
