However you seem to speak as if you know for a fact that “good clubs” have all these strict rules and there’s zero chance of funny business.
I have to admit the ‘good clubs’ thing stood out to me, too.
We have no idea exactly where he went (since he conveniently withdrew cash 🙄), so it could’ve been a ‘good’ club, an ‘average’ club or downright ‘seedy’ club.
And given there are unaccounted hours after the club may have closed, we don’t know what may have happened off-premises, when clearly there is no regulation about what goes on, whatsoever.
This ‘good club’ aspect of the argument seems remarkably flimsy, and yes, naive.
Perhaps it’s being used to provide the OP with some hope that all is not lost. But given that being in the club itself is merely the tip of a much more treacherous iceberg, that ship has sailed (and sunk).
Porcelain - I agree with others that there is no rush to make any decisions, although like you, the thought of sharing Christmas Day with him would be unbearable. It sounds like you have family around for support and options.
