I am a financial adviser and one of my great aims to bring women to the table when I take on clients. It is so disheartening to hear "oh my husband deals with all that".
Both spouses, as a minimum, need to understand what assets they have, what income they have, and what they're expenditure is.
Too many times I've seen widows all at sea because they haven't a clue what they have and where they have it.
Also, you see those sad face Daily Mail articles where the husband takes out a single life annuity (for the maximum income!) then promptly dies, and the widow is left with nothing. Of course its "the bankers, the insurance company and the evil IFA" that are to blame, not our dear old Gerald.
My advice to the OP is to sit down with your husband. Get on the same page. Talk about what you both want out of life, and how you will use your assets, incomes and potential incomes to reach those goals.
It appears to me like you are both in your silos and not seeing beyond the end of your nose, let alone each others perspectives.
You are married, Talk to each other. If he truly won't engage, maybe then you might want to consider whether the control exerted is a marriage or a captive situation that you would be better out of.
