I do not think you are misinterpreting my posts at all, I think that the approach of re-establishing the friendship through casual contact and interactions is sound advice and I trully believe in it.
I believe it can work as outlined by MWD in DR and DB.
However, when there is an affair present in the situation none of those things can start until all contact between the affair partners has ceased. NO EXCEPTIONS.
^^^^ This point should not be overlooked.
