I don't love you anymore

W copied me on a letter she sent to the lawyer today, asking for him to draw up a legal separation document. She probably thought she was doing it out of courtesy, but it was really just a kick in the gut.

Has anyone here on the forum had an experience with this kind of document? Apparently once it's drawn up, I have to sign it to acknowledge when our year of separation started (which is required in MD before divorce). Is signing that giving my OK to divorce? Does that legally mean that I am OK with this? I guess I just don't understand it, and it kinda sent my head spinning today.
