i would go with texas jack move. decline and counter offer for a different day. she did apologize for not responding but remember the op texted her A FEW DAYS AGO. this is unnaceptable. if she had texted him back the next day, apologized, then i would respond and try and set up the date for that night. but the fact that she texts him back DAYS LATER shows she is a major flake and expects him to be at her beck and call when she is bored. she could have easily texted him back within 24 hrs, said " cant tonight, how about xx ?" but no she just blows off his texts for days later then she expects him to just ramshackle all his plans for that day ? lol. ridiculous. i would simply say after she apologized ( this is important) "haha, its cool. cant tonight, busy. tomorrow at xx, first round is on you ".
