I don't really know what your situation is, I guess, but it seems there is still reason to hope. Especially since he suggested counseling and there's no OW.
I also had a bad experience with a couples therapist. She knew about the affair 3 months before I did as it turns out, so I feel that all subsequent sessions were a sham and that I lost valuable time when maybe we could have made some progress before the A progressed to the point where my SO can't let her go. Sigh.
I have my 3rd coaching session tomorrow, thankfully. I'll probably spread them out after that, too, because of the cost. I get that.
I sincerely hope it all works out for you and your kids.

Here's what Fogg wrote to me on another post.
"We all have been there reading one of the success stories and feel that sitch isn't as hopeless as our own. It's just the perspective of it being our own pain, our own suffering that makes it feel that way. Any sitch could be a success story and theres hope for all. There are no guarantees of R even if you follow DB so we do need to accept things may be over for good, but don't let that discourage you. With or without them if you follow the DB principles you will be a success story one way or another." I hope it helps you.
