A large majority of the posters are fixers. Sharing with someone who has "left the building" is difficult because you now need to step back and only share some of what you use to share with him. It is difficult I know...but you can't share everything with him at this time. You can share what's happening with the children and bills (if need be), but what is going on in your life...share with a close friend. He needs to miss you and be curious in order for him to one day rethink what he has done and question whether he did the right thing.
You are doing just fine. We are all 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.
