Lois,
He may not be taking the AD's now because of the drugs, etc. He may think that the drugs are taking care of his issues.

Please keep your focus on you and most importantly your daughter. She's going to need all of your support right now.

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.
