Her and her boyfriend might be feeling very in love at the moment, and she just might have forgotten to call you recently. When someone has moved in with their loved one, they feel very in love with them, and forget all family. I'm sure she'll come around eventually. Maybe she doesn't have any internet connection or credit? I think you should wait a while to see if she contacts you, if she doesn't by Easter then call her and email her more. I hope she does get in touch.
