First... get all your finances and legal work taken care of. You need to protect YOU.

Then I would tell her, "I don't want to end our marriage, but I won't stand in your way. I respect your decision but I disagree with it. I'm sorry I tried to hold on to you when you didn't want to be held." No sarcasm or extreme grief. Just a gentle sadness but determination to move on.

Don't keep worrying that you'll say the wrong thing that will end all chances of reconciliation. Thats not how it works.

If she realizes it's not all sunshine and rainbows out there, and she wants you back, she will come back and try. In the meantime you'll use her absence to focus on you and being the best man you can possibly be... and for YOU, not for her.

And the above is the speech I gave myself so many times. Just FYI. I had to tell myself this over and over and over.
