I checked back on your thread and can't actually tell if you have picked up and read "Divorce Remedy" by Michelle Weiner Davis. It's often described as THE workbook for Divorce Busting and the work we talk about here.
Please do pick it up and read it, now.
As a WAW, you have already (initially) gone through the Detaching and GAL process. It's pretty common. So what is ALSO common, is you are now at a point where you've reconsidered and now want to see if things can be worked out.
So as you indicate, GAL is NOT a problem, for you. Keep doing that, as it will continue to be helpful for you, to some extent.
As you go through the DR book, there will be a number of key elements that you will really want to work through. Things like "Starting with a beginner's mind", "Knowing what you want", and "Asking for what you want".
At that point, you will probably be looking at focusing on 180s. The things that you want to work on, make better for yourself, which may also be things your H might have complaints about you, as well as things that might help your H trust you and believe that life with you, from this day forward, would be much better.
And finally, there is another book which is often referred to here called "The Five Love Languages". It will help you possibly understand what YOU need, to feel loved, as well as what your H needs, to feel loved, and how that dynamic can cause problems because we don't realize we ARE being loved and that our loving actions may not be seen as loving actions by our spouses, and how to change that.
So... please pick up and read the books...
And...
With a beginner's mind, not that the two of you don't have history, but rather from a perspective of "Life between the two of you BEGINS NOW and is NEW", you can move forward.
You already know that you would like to try to work things out with your H, so that's clear.
So...
Just to be clear, your H has asked you a couple times whether you would work things out and you weren't ready. Have you now told him you would like to work things out? No subtle hints to him. Have you actually said to him, "H, I understand that you are moving forward in your life. I am working on myself to become a better person and am making new, better choices, now. I would like you to know that I am interested in working things out with you and staying M."
No "if's". ie. Not "if he ends the R with OW" or "if he is willing". You want to be very clear that you intend to work on the M.
He MAY NOT believe you, right now. Still, you need to make that clear to him, verbally. And THEN, you need to SHOW HIM, that you are doing so, with 180s and other positive, consistent behaviour from yourself.
