It appears that things are least going in the right direction. As for the OP, until they are completely out of your S's lives, you can not trust that something will not happen.
My H and I were back together working on things, having a good time, enjoying each others company, but he had not given up the OW completely. He still went to the same gym that she goes to and was not in a place yet to share his e-mail account with me, but he was home and with me almost all of the time so I thought we were doing ok. Well, he was doing ok because he had me and her. He has since moved out (at my request) and I have begun detaching. He now seems more interested in me then ever. We still do things together and I make sure we have a good time, but I don't do them as much as I use to. My DB coach told me that I was too available and that I needed to have more quality time and less quantity time. It seems to be working. Don't know if this helps you or not. Just seems like the 180 really gets their attention.
Take care and hang in there.
