"My wife has definitely noticed the changes in me (exercise, dogs, training, playing more music, therapy, meditation, etc.) and they've been consistent, which I think is the most important part any time anyone makes changes."
While those changes are great, they aren't the crux of your problem. The problem lies within your W and the struggle she's going through. You can change all you want, but it doesn't get down to the root of the why your W isn't "into it" right now. Give her time.

Emotion, yet peace. Ignorance, yet knowledge. Passion, yet serenity. Chaos, yet harmony. Death, yet a new life.
