Yes that gets to me too !!! It seems like these are what I like to call the "special" dcp . I don't know about your situation but for me these are the ones that never want to conform to rules . That believe they are employing you ! My 'special' dcp had many excuses for not getting back to me but I would get multiple texts from them on my personal days if I didn't respond in an appropriate time .
Maybe they were away from the phone or truly busy ! In my experience it was disregard , and eventually we parted .
