<human>: Give me the gist of the text in a nutshell

My wife and I are both in our earlier thirties.  Married for 2 years and together for 9 years total.  I work full time, and she is a stay at home mom to our newborn child.

Lately, my wife has been making several trips to the ATM each week to withdraw $40 here...$60 there.  This week alone, she has withdrawn almost $200 in cash. 

We make 99% of our purchases via credit card when we can.  So it is very out of character for her to be withdrawing cash so frequently.  

When I asked what she needed the cash for, she got defensive and responded "I am tired of being treated like a child!  I don't have to justify where I spend our money!"  But she never did answer my question.

I am definitely the "bookkeeper" of the house.  I like to budget and account for where each dollar is spent.  So I understand how I can be a little controlling over our finances.  But it drives me batty to not know where our money is going.  And drives me even crazier that she won't tell me out of spite because she feels like she is "treated like a child."  

Should I back off and just let her spend the money at her discretion?  Or do I have a right as a husband to know where that money is spent?
<bot>: Wife has been withdrawing small amounts of cash frequently.  Won't tell me where its going.  She accuses me of being too controlling.  Do I have a right to know?
