Sounds like the day was enlightening for both of you. You've given him a lot to think about and right now, he's feeling a lot of guilt and shame for what he's done. Right now, he doesn't see a way back to you to reconcile and begin a new marriage.
Do you want to try and save your marriage? If so, you have the key. What is the key, time, patience and forgiveness. Show him that you can forgive and be a friend. Sure, he doesn't feel anything for you right now and that's the depression talking. If you are in no hurry to push for a divorce, then sit a while unless there is an absolute need to do so to protect the assets, etc.
Again, you are the key and if you have to decide exactly what you want. If you want to wait a while longer, then wait, but do not allow others to push you towards a divorce unless you are ready to do so. If he wants a divorce, then allow him to do the filing. Time is on your side...truly think about what you want. If it means taking some time from the forum and doing some soul searching, then by all means do so. No matter what you decide, we'll be here for you.
Sit quietly, the answers will reveal themselves when you least expect them to. The past is gone, the present is a gift and you need to focus on today, allow the future to reveal itself when it is ready.
