MoveFrwd - understood. But being as how I don't approve of the D (she did not try to work on anything and just threw in towel.. most likely thinking grass is greener with EA / OM) - I am not in a rush to go from marriage that I had no idea anything was wrong to legal D within now a month and a half.
As I read my state laws - you have to have "Irretrievable breakdown in relationship for a period of at least six months" in order to file for no-fault. I am not sure how that time frame is time-boxed, I assume from BD which was right around new years.
