Be respectful of your feelings and your soon to be exs, don't celebrate it unless your heart is telling you its not over...you could accidently lead your spouse to believe its not over.
Have a divorce party.
It depends on what your relationship is right now. If it's tense and hostile, I wouldn't mention it unless he did. If it's fairly amicable, I'd think you could mention it.
I live downstairs, and she lives upstairs. That's how we are coping for now
Press Ctrl, Alt, Del- be busy out of the house
Does he know you are "soon to be divorced," or is it going to be a surprise? If he knows, then I'd let it pass. If he mentions it, maybe the best answer would be to the effect that you both started out with good intentions, but it just didn't work out (or something along those lines). Keep things as amicable as possible. You will probably continue to have to deal with each other after the divorce is completed. Nobody should judge anybody in such a situation because nobody knows what all anybody goes through....
Well, it's just a date now, you can acknowledge it without celebrating it.
I assume papers have been filed if not signed already. Correct?
I'm not judging, I'm just trying to get some perspective.
...and I assume there's no chance for reconciliation?
Why thank you Sweetly. ;)
