I think you are doing well and your starting to make an impact on your W. She is noticing the changes and is open to expressing some guilt about the current sitch. This may take a while, but at least you know she is thinking about your sitch. She probably had a lot of time to think without the kids.
Just remember she is likely to be very cautious about any step she takes toward you, so these little comments and opening up to you are not insigificant.
I agree with Forest, when you are ready, take advantage of those oppportunities to hang out as friends, I feel that will bring you closer together quicker than anything IMO. The important thing is, you have to ready for it. These will give you excellent opportunities for your W to see your DB in action and the new Neil.
Don't worry too much about the pity party. One of the loneliest weeks for me was when I had my kids for the first time since separating in my new place.
