This seems like a ridiculous anecdote that is unverifiable by anyone but the author. We even had names for these when I worked in journalism. They were called "sure it did's" because everyone was "sure, that's how it happened." Amazingly each week we had a handful of op-ed pieces or even real reporting that would open with an amazingly pertinent, often hard to believe and never verifiable slice-of-life just like this.
It's not like sleeping with a girl and then vanishing never to be seen again is some unheard-of event. There's a whole genre of country music on the same theme.
Not ridiculous. This is the kind of encounter that occurs with “yes means yes” laws which are being prepared/discussed/implemented. In the age of #metoo you basically need a contract ahead of time. Women aren’t exactly safe to be around if you meet particular criteria.
