Nah....
Thats like getting married for money

And worst of all its not even a lot of money
My wife is going to work (till we have kids)
We going to pool our money into 1 account
We take all expenses off of there at once (house/petrol/groceries etc)
75% of the money left over we put in a savings account
the other 25% we split 50/50
She can then go for a hair appointment, spa, buy new shoes, whatever she wants to do with her "cut" and I can do whatever I want with my cut.
Basically covering all expenses + savings then opt for luxuries etc
This way money never becomes an issue because we both will have the same amount.
So if she wants to be a nursery school teacher than earns R3000 and I bring in R32000, she gets half of the 25% left over each month after expenses + savings
Even if its more than she earns.
The idea is to pool both our money into a single account so I don't have to hear her bitching about controlling her and thinking just because I make more than her that I can choose wtf is going on. Same way I can't moan at her for not living within her means and not contributing to the household because she keeps faffing with her hair
