If I put my husbands money on the line I already know how he will start advising me and before I know it he’s making trades with me and starts to dominate the whole thing.
Regardless of you as a woman allergic to advice, your proposal to ask for a loan is certain to be rejected because of collateral rules. Also your reasons, almost all users of this forum welcome the advice: "Borrowing money to trade is strongly discouraged". This is the basis for experienced borrowers supporting reasons to reject your request.
Unfortunately, you don't stand a chance here, do it somewhere else.

I know my husband, this is just who he is.
Is it also the other way around? Don't say that this will be the stupidest thing you've ever done.
