I went to market with my wife to buy things for our new born baby, after my wife selected baby things that Worth thousands and I paid with my btc,the transaction was very easy and faster. When we returned home ,she asked if you die can I achieved your btc or continued with your account? Because it's very easy and faster in trading and transaction.
Sad to hear that Your wife is much concern about your Bitcoin than your life 
how can She even ask that straight in your face? and have not you dare to explain Bitcoin for her in long time? imagine that you are already Married yet She knows nothing about bitcoin ? are you just making some story here and nothing is truthful?
because considering that you are already married you should have explained to her what is bitcoin and how you accumulate them.
