I would have a discussion with him today, when he gets back in, and tell him (remind him?) that, whatever he thinks, you fel that is private and you really don’t want him discussing those things with anyone other than you again please.
Even if he thinks it is you that is odd – and I don’t btw, I think in the UK at least it isn’t socially ‘normal’ to discuss your income etc with other people as a general rule – it doesn’t matter. You don’t like it, and he should respect that.
If he then did it again, I would say – yes, in front of the friends – that I’ve already told you that I don’t think anyone else wants to hear that level of detail about our money, so please don’t carry on telling everyone about our finances.
