I think I understand your point here. That we should wait and verify facts before getting upset with people when they don't show up to things or don't do certain things we are expecting of them. Is that right?
About 3 years ago I bread my male German Shepheard with a female German Shepherd that belonged to a friend. As the owner of the female, my friend was responsible for selling the puppies after I got "pick of the liter". A guy was on his way to my buddy's house in Illinois from Pennsylvania to buy one of the puppies. The guy didn't show. Found out he got killed in a really bad car accident in Indiana on his way to Illinois. It was very sad. My friend ended up keeping the dog for himself.
Let me elaborate a bit on what I was getting at.
I've seen tons of threads on this forum from men complaining about getting flaked on, stood up on a date, ghosted, etc. You'll then see other posters on the thread try to dissect the interaction leading up to the scheduled date. Then they'll start doing a deep FBI level analysis and say you were texting too much, you weren't texting enough, you didn't lead properly, etc. These people, including the poster that was stood up, will immediately jump to some strange conclusions or come up with some intricate details to explain why this occurred. However, they don't consider that maybe something legitimately happened on her end. Maybe her dog got ran over by a car, maybe she got in a car accident, maybe she her grandmother is sick in the hospital or maybe died? Maybe her friend broke up from her gf and went over to her place to vent, maybe, maybe, maybe.
The reality is that IF you were flaked on or ghosted you almost always can assume that at that given moment of time she is NOT available. At the end of the day, when you are in the early phases of the dating period you really aren't that high on her list of priorities. In fact, a lot of men seem to forget that you are barely past the stranger phase, though this is not the case with your specific story.
