Although some day I may choose to be a stay-at-home mom, for now I am a working professional and it would be very hard for me to make the transition to asking my husband for money for personal things. I'm pretty financially responsible, but I still don't like to have to answer to someone if I want to spend some cash. I like to spend my own money especially when buying things for my side of the family, and I also would feel it so awkward if I wanted to buy my husband a birthday or eid gift but was dependent on him for the money to do so!
On a related note, I'm all for balanced partnership and understand the ideal of the man as a provider, but I also think one of a woman's most important resources is to have the ability to provide a good life for herself if necessary. Too many women are financially dependent on their husband to the point that it leaves them much more vulnerable to abuse or totally dependent on relatives in the case of divorce, death, abandonment, etc.
