@Emm2013,
I hope the assets are in both your names. You should have joint savings and checking for household needs, family vacations....whole bunch of things...You both can have individual accounts as well...My husband and I do, we pool most of the money but we still have a "whatever I feel like" account for whatever.
The house, all the cars, investments, banking needs are in both names (It works for us) we discuss major purchases like cars, big ticket items for the house, renovations, etc.
My husbands income has always been greater than mine, that doesn't make him the senior partner or me a dependent. We both made enough money to live independently before we got married, but we lived a lot better when we combined incomes.
I think it's unwise for one spouse to use their entire paycheck to run the house, especially when the other spouse is salting away 'plenty'. There are a number of reasons for that, one...if your husband was seriously ill and unable to handle the finances..you can step in...otherwise you won't have access to any money thats only in his name. If the worst happened and he dies, you will need to make funeral arrangements and it's so much more difficult if all you have is $400 in your savings account. Plus you don't want anyone else top lay claim to any assists the two of you have.
The same advice works for him was well, he needs access in emergencies...
Paying the mortgage and utilities doesn't make him the senior partner, you pay medical insurance, daycare, doctor appts, clean the house and make meals (carry out counts) bet you do the laundry don't you? Laundry's a big deal when the kids are young, sheets, towels all need to be washed and changed regularly. I suggest you hire someone to clean the house at least once every two weeks and tell money bags to pay for it. It will lessen the load on you and you will have more time for your child and other things like hair, nails, whatever. And for God's sake, quit calling him the 'Breadwinner'. You are not living off his charity, you're his wife, he's your husband and you both share responsibility and any good fortune that comes along.
If you don't know what the monthly expenses are or how much money is coming in every month, find out. You should know everything, how much is left on the mortgage, the rent and other expenses for the business (and that's his job, just like you have a job) Just please please please keep track of these things...not because you can't trust him but because you have to know these things. Money is not a special commodity that only 'bread winners' understand. Since both of you are breadwinners, get informed.
I'm not lecturing you, honestly if you were my daughter I'd encourage you to do the same.
