Timing is everything ... I know you are in the right spot and your heart is in the right place ... but to soon, this would add pressure, you just planted all those choice seeds and in my head you are stomping all over em with this one.
Now if you do this on your own, off to the side ... keep it a TOP secret ... let the A run its course, lets think best case scenario and W gets her wits about her again .. you two start to reconnect and she finally admits her mistakes, shows remorse and you begin piecing ... what a wonderful gift for a birthday/Christmas ... rough drafts that show you were busy completing a project you started with her during the worst of times.
To toss this at her now ... honestly IMO .. to much ... she has alot on her plate she needs to finish first.
