Does your spouse KNOW you filed papers? And is he/she wanting a divorce?
If they are wanting to work at it and you are simply leaving, then you need to wait until after court.
If you are both calling it quits then whenever you consider yourself officially done with that person.
When you do not love the person anymore and you know for sure that the divorce is in motion (papers filed) then you can take off the band, because emotionally your not married anymore.
