WOW! You are a speedy runner. Your easy, get-back-into-shape pace is faster than I will probably ever run. Forget about your real pace. I am impressed!
If you look at other threads you will see that many of us wonder how they will see the changes if they are not around. I think they can feel them. Maybe that sounds hooky but I believe it. Plus, sometimes they do not have to be around to see them. The fact that I never call H or email him without contact from him first - total 180. I do not care what sort of "fog" he is in, he is not braindead, so he notices.
Your wife will return from Germany to a Christmas tree. A job she used to have to do. She will notice. Another bit of advice I have gotten from the good people here. Do not expect her to comment on the changes or give you credit for it. However, this does not mean she has not noticed.
I was just driving home from a movie and got caught up hoping to come home to a message from H and wondering how after 4 months and he is still miserable and tells me he is miserable, he cannot see it was not "us" or at least not "us" alone. I have managed to work myself into quite a foul mood so I am off for a run.
