My XAH still loves to text me (I won't speak to him on the phone) when he gets drunk. It absolutely ENRAGES him that I won't engage. I would hate to be in the same house and hear it. Lucky for me, I don't have to be. I turn my phone on do not disturb and move on.
Keep doing what you are doing. Eventually he will wear himself out. But...he will continue drinking. So, what plan have you made for your own future?
