Congratulations on the weight loss. I'm glad to see that you are taking care of yourself. Keep up the good work!
The changes usually begin about 18 months prior to the "speach" that they give us. They are very subtle to us, but others can see the changes much clearer than we can.
As time moves along, others will also begin to mention the changes your h was making and one day, the entire situation will become very clear to you and then you'll have a better understanding that this didn't change over night.
Sit quietly, the answers will reveal themselves when you least expect them to. The past is gone, the present is a gift and you need to focus on today, allow the future to reveal itself when it is ready.
