The other thing you need to check on ASAP is the fact the two of you had sex this weekend.
You mentioned in an earlier thread Adultery was an available ground to file under. In NY if your spouse has an affair and you sleep with your spouse AFTER the affair you have conceded to the affair and no longer use the legal grounds of Adultery. The statute is SEVEN YEARS in NY.
Since your W did have an affair and you did sleep with her before anything legal was filed there is a good chance you have removed the Adultery ground as an available ground to you since you had sex with your W.
This is why talking to an attny is so necessary when Adultery is a ground to file under. All states differ. Your W might have known that all along and now has protected herself even further.
