Help boyfriend & & money

So my boyfriend is really bad at budgetting he’s money he gets paid fortnightly and as soon as he gets paid he’s happy to go to the pub with he’s friends and all this by then by the time he’s waiting to get paid again it’s me paying for the majority... and I just think while you don’t have money why don’t you just not go out? And actually save the money that your gonna need sooner or later
