I am glad that their has been some improved communication but temper your expectations and remain as neutral as possible. If you can get there,have no expectations, but I find that is a difficult concept to master.
Don't get down if he pulls back after this week or if you feel he doesn't notice any changes that you are hoping he sees. He most likely will see them but may not communicate anything to you. And in the mind of a WAS these changes may confuse him and cause him to think about a few things which I think is a good sign but it also may manifest in anger or him going dark for the short term.
