That sounds like pretty good news. I would really try to refrain from talking any more about your changes, even if she asks.
As for where things go from here, again, I hate to say this, but just like we can't believe them when they say there is NO WAY the marriage will ever work and the only solution is D, we can't just believe them when they say the A is over and they want to work on us.
The most important thing for you now is to make sure, absolutely sure, that you DO NOT just fall back into your old marriage habits again. Your old marriage did not work and is over. This new R with your W should look and feel much different, if only because YOU have grown in the meantime to understand what YOU need to do differently. Please, don't make the same mistake many others have made of thinking that just because she says she may be willing to work on things it's time for you to change what you are doing. It's not.
It's time for you to kick DB into high gear, making sure that you do NOT put any pressure on her and that you do NOT form any expectations from what you heard this morning. Expect nothing except from yourself. Let her have the time and space she needs to process this. She may indeed break things off with him, or she may not, but the seed is planted and it WILL grow if you give it time and most of all, nurture it with YOUR own growth and understanding of the process.
This IS a process. It is a process of discovering that in you that will make you the best man you can be and then WANTING to be that man enough to do it in front of your W. For your W, she is now just starting to see something positive and needs time to believe that it is real and not just something you are doing to win her back, which is why it's SO important for you to keep on your track and not fall back into codependent behaviours because she's "back" now.
I think you did really well and from the sound of it, I think you have good reason to be happy today. This COULD be a major turn, just make sure you LET it happen and don't try to pull her the rest of the way towards you.
