My Story again with paragraph breaks. Sorry.

[Swiss Miss]

From my experience he is still in contact with her. I went through the exact same thing with my husband, some strides forward and then, out of nowhere, huge steps backward. And when I found out the whole story I could pretty much pinpoint when they'd had contact and then broken it off again based on the events in our R. Of course he maintained, when we still talked about it, that she had nothing to do with things between us.

What has worked for me is to let him make contact and I end it first, and I can tell he'd like to talk or stay longer. I'm certainly not a success story at this point, but cutting him off did not seem to be the answer. So now I make sure I've left enough room for him to contact me but I never, ever pursue. Our sitches seem similar, but luckily you've found this website a lot earlier than I did and while your H still sounds somewhat interested in making things work.
