If you are going to do yourself ONE favour in all of this. Act as if she is some new girlfriend you are interested in. Act as if there is no history except for this new R.
How would you be different if this wasn't your W? If this was some new person in your life that you were getting to know and starting an R with.
Because if this was some new woman, while you might hope to build a stronger R with her and you would go through all the normal stuff with dating, etc... You DO NOT have her and she could stay or she could go...
That, to me, seems the best course of action.
Congratulation on your new girlfriend. Hope things go well for the two of you...
