I have to add here that my stbxh said the same thing :see if we make it etc etc while he was still seeing the OW on and off, mostly when our interactions were unpleasant...
From what I read, after the initial effort to break it off with her, he strung her along with no clear indications of what it was she should be waiting for. One recent mail she sent him was about this year's vacation where she asked him, what "let's see what me and Maria will decide on vacation...'.
So, cake eating and making sure he had someone waiting for him in case I did as I told him, file.
I think this is an important turn for you. Proceed with the filing. That's my advice. K
