Wife just told me doesn't want to be married

[witz10]

how do i stand in front of her and tell her how i feel and gain my ddignity back. When i look at her in the eyes i lose my words should i write it out in a letter and give it to her or read it to her. In a neutral spot no kids around. I deserve the right to voice my opinion but do i risk the chande of losing her. Should i just write the letter and know i have it and give it to her down the line
