There may be some backtrackign on both their parts over the course of time, but that's no reason to get discouraged.

If there are signs of them both TRYING to end things... and you know YOU calling HER home is a BIG STICK you can use if you NEED TO to get them back in ORDER again it I think the worst is over.

I really think OW hates you poking around her home and her husband... and so does YOUR husband. I think this is a very useful tool to keep them in line.

If OW knows any contact from her to your H is gonna launch YOU taking a fight to her doorstep it looks like you have given her very good cause to reconsider the value in pursuing your H any further.
