After going on a first date with a girl and kissing her, I invited her for dinner at my place for the second date, and she preferred to go out to a restaurant. I accused her of being high maintenance and she got offended and wanted to just be friends. I texted her and left a message about hanging out as friends - no response. I saw her a month later and she approached me, asking me how I'm doing. When I asked her why she never responded, she said she changed her number and I told her to call me - she did not. I JUST texted her old number and she responded, asking me how I'm doing. What is going on here?
