Starting off, he's your husband and should be aware of everything you do except the marriage was forced, thinking or concluding about the discussion being unnecessary should be his to decide.
and when it comes to marriage, we should all inform them especially if there is money involved because it can even start or cause a fight and misunderstanding, maybe in the end it will even be reprimanded. Others say that our partners don't need to know all the moves, but for me, when you enter the world of marriage, what you have will automatically become his too, so they should really know everything and if you have respect your partner, you won't keep secrets because at the end of the day, you two will be on your side and will help each other especially if there is a problem.
