We went to a counselor and when he found out that my XAH was actively drinking he refused to see us any more. We divorced over a decade ago and he is still very actively drinking. I am thankful that I am not a part of it.
If he insists on a date to come home make it a year from today. That is not too much to ask if he truly wants to work on his sobriety. You also need time to process everything and decide what is best for you.
