I guess to clarify my question, it's more about do I respond if W asks what changes I'm making, or do I blow her off?
Yes - any and all changes would be for me and my son, not for her benefit.
If she has to ask WHAT changes you are making then she hasn't noticed apparently. If she states that she has noticed you are making more frineds and being more social (for example), that you HAVE made changes, then simply say: "Yeah, and it feels great to do that!"
