My AH went to intreament too but in our case the conferences were face to face.
I didn't "spill the beans " on him as he was pretty upfront with all his stuff.
They will get to the bottom of all their "problems" when they are in treatment and no stone goes unturned...so i guess it would only be a matter of time before this issue came to light.
I wouldn't worry about what you did but I can understand why you are scared.
I hope it all works out for the 2 of you...and I hope you are using the time he is away to be good to yourself
