I'm shockproof, bombproof, and fireproof, but your post is one of the most SHOCKING EXAMPLES of financial and emotional abuse I've read on these boards and I'm incensed at your h's injustice to you and your dc.
Wtf is going on here??!! You work full time and cater/clean for 2 lodgers yet you can't treat your recently widowed mother to lunch or the cinema, or socialise with your friends, and your dc aged 15 and 18 have no money to call their own? Your h is a strong contender for the Mumsnet Controlling Twunt of the Year award and it is high time you put an end to his insidious poison parsimonious ways.
I see no reason why you shouldn't be economical with the actualité when implying to your h that your new employer requires you to set up your own bank account to receive your salary/expenses, but pull no punches when telling him that in future you will be transferring sums from your account to the joint account as and when required upon sight of bills and as dictated by the need to fund other household outgoings.
I suggest you also tell your h that you will be setting up bank accounts for your dc and that sufficient monies should be given to them monthly to fund their travel to and from their place(s) of education together with clothing, toiletries, entertainment, etc, so that they can begin to learn the value of money and how to budget for expenditure on gifts for family/friends at christmas/birthdays, holiday spends, and so forth.
I'd love to be a fly on the wall when you break the news to him and it may help you to visualise all of the responders here who've expressed their outrage at the way you've been exploited shitting on buzzing around his head if he proves to be less than enthusiastic about ceding control and allowing you full sight of your joint finances.
Good luck for tonight... but you shouldn't need it as yours has to be one of the most righteous causes I've encountered of late.
