We all got different cases but It is good sign and a good read that both of you talked and sit down about your finances/money matters ''before'' the marriage.
My husband and I did the same (talked and sit about our money matters before the marriage)...we both agreed that he is the ''provider'', even if I work or not it doesnt matter , sometimes he is the one to remind first if i want to send money for my family( no particular amount just a gift for my mum and ''not'' to support all the family) and even when I started working here in the UK my salary hasnt been touch to pay big amounts of expenses (its always his account that carries all the bills) my account is our savings ...when you get married you ''share' everything its just down to both of you to manage your finances.
My only suggestion is to ''remind'' your Mahal's family that ''it will not be the same'' as it used to be when she provided for her family as she is going to start a family of her own soon.
