I need your Advice, Should i Tell my Wife my ATM PIN?

Hello Ngisters,

I need your advice here, I got married to my wife 6 months ago and everything has been great since. Last weekend, we were at the mall together and i wanted to withdraw some cash from the ATM and she stood right there like she wanted to see my pin and i told her close your eyes ooo (My Bank says so).

She got annoyed and she turned everything to a trust issue that i do not trust her bla bla bla. Now I'm wondering should i just tell her the PIN and have peace or insist on my privacy since we operate individual accounts?
