I had my ex-girlfriend hit me up after about 5 weeks of no contact after seeing one of my stories on Instagram. When she video called me I picked up and she asked me if I was busy. I told her yes and she told me to call her back when she wasn't busy. My original line of thinking was to just not call her back and just let her call me back some other day. But after about 4 hours I had reasoned to myself that I had told her that I was going to call back so I did and she didn't respond yet. Was this the proper response, and if not what was, and what would be the best course of action from her fourth if I wish to at least smash again in the future.
