So the past two girls that I have been talking to, both insinuated interest in me first. They both asked me to spend some time so we can get to know each other better, but both times, when I arranged my schedule to make time for them, they decided to flake last minute and they apologized saying things have been really busy for them. I replied, no worries and moved on. I am just wondering what it might be. I am thinking that maybe I am not showing enough interest back.
