Girl I have been seeing went away on vacation for a week. She told me the day she left I can text her whenever I want and to use the whatsapp, app. She then wrote I hope to see you soon. We have been texting on/off as she is away. However, she hasn't been the one initiating texts its all been me. Today I did not text her at all and she did not text me either. Should I be worried or am I overthinking? Is she still interested? Or is it because she is on vacation the reason she is not initiating text messages?
