Good luck. Maybe it'll help you cope today if you formulate a DB plan for tonight. Such as, listen and don't talk. Really hear him. If he says something like I definitely want to move forward with a divorce, say something like I understand that you want that, I get it, and it sounds like you've been really unhappy, haven't you.
Let him get it all out.
Plan, perhaps, to have no answers for him. Whatever he asks you can tell him, let me give that some serious thought and I'll get back to you. He's had time to think about what he wants, and you may need more than 10 seconds to respond, and can ask for the time you need to sit with this and get used to it.
What that will do is let him feel heard.
If it helps any, he's probably having an uncomfortable day. It's not easy being on the other side of a "we need to talk" either.
Good luck. Ignore the anniversary; we've all been there and afterward, a day later, a couple of weeks, later, two years later, it'll just be a day. Don't torture yourself by giving it more significance right now.
