If grey’s other opportunity didn’t work out, they probably would have unashamedly reached out to green again for a new date, if that exchange hadn’t happened.

Non-zero chance they will anyways, especially if grey is a guy.

Though I had a woman get surprised and upset when I declined a 3rd reschedule after she went uncommunicative twice when I asked the “we still on today?”. Apparently she didn’t have a mobile plan or internet at home and had to go to some public WiFi to communicate and both times had shit come up with her kids, though the second time was her son’s birthday party, which isn’t something that generally just pops up on you by surprise. It’s not even punishment, just the emotional rollercoaster before we even had a first date killed any interest in having a good relationship with her, just like that cancelation message in the OP would have.
