Hey there
Glad you had a nice visit.... keep your fingers crossed.
You layed down your boundries, now its up to him to decide what he wants to do. You have to let go of it cuz its not your issue to deal with, if he drinks again you know what will happen so dont worry about it now. Enjoy the time to take care of you... get a couple Al-anon meetings in and enjoy what is happening today, cuz that is all you cant control.
I sure hope it all works out! I will cross my fingers for you too
