I'm so sorry that you've had to deal with this. I know it must be very little consolation, but it seems that your H is still holding back on taking that relationship further, whether he puts married in quotation marks or not. At the very least I'd say your H is confused, and confused is better than certain.
Seems like it was a 180 for you to share your feelings like you have, and given that you haven't been doing this the entire time, I'd say it was a good thing.
I don't think that there is one right way to DB. I think DBing is more about finding what works for you, taking 180s and risks, and always showing how much you value your partner's opinion and process. Some of the times where I have seen the most progress in my own sitch has been after taking a risk, or behaving in a way that others might suggest not to. Maybe this makes things worse for awhile, tenser and such, but then you can build on the truth that has been exposed. Now is your opportunity to step back and see what happens next.
Keep us posted please and hang in there,
ITH
