I know the ball is in H's court whether he decides to stay or go.
I don't know if I should "detach" or keep on with building a happy, harmonious family life that includes him.
His goal to build trust and be honest doesn't mean he will stay. He says it will be necessary to have a healthy relationship with me so that we can coparent in a positive manner if he leaves.
So keeping in mind that he may leave, I don't know if detaching and giving him space to think serves me better if I want to save the marriage.
Or if acting "as if" we already have a happy marriage is better.
