So here's the background. Been dating a girl, lets call her Sally, for about 5 months. She goes abroad on a trip for 5 weeks that she's had planned since before we met. We talk (almost every day) and video chat (about once a week) through various means.

Right now she's staying in a hostel with a bunch of her friends and she starts complaining to me that all of their boyfriends are Skyping with them every day and why don't I care about her and that I never am the one to initiate the conversations.

I told her she knows my schedule is busy (something she admitted to) and the time difference makes it hard to talk but that I would contact her soon. We video chatted a few hours later once I was free and it ended with her saying, "I hope I don't have to be the one to initiate this chat again hopefully you video chat me on your own prerogative next time."

She's back in a week. How should I handle this? The accusations of not caring are really annoying and I want to settle this in a way so she knows I haven't done anything wrong.
