I don't have a success story but I thought I could give you a little hope. Just remember, hope is everything right now.
When my H left, he used to say the same things. Divorce, divorce, divorce.....29 months later, we are not divorced. I think in the beginning they have it so stuck in their heads that they want a divorce that they don't think about anything else. Once they have time to think things through, they change a little. Your H seems to be going through the stage of not knowing what he wants. Give him space and see what happens.
Do not talk about the relationship or anything else right now. Go to the CA and see what happens. Don't expect anything from him in regards to being different after the meeting. Let him leave there and give him time to let everything sink in.
It takes a lot of time. You need lots of patience (which is sometimes very hard). If your H says something that upsets you, think about something that makes you happy. It helps to deal with it.
Try to stay busy and not think about things. As I tell everyone, think positive.
