So sorry about your troubles, and most especially the loss of your mom.
Good for you for getting him out. And thank you for posting your story. I think it is helpful for others to read about what happened to you. We come in here thinking if they would just stop drinking, presto, change-o, we would get our happily ever after.
And it just doesn't work that way.
The important thing is you were strong enough this time around to know what you know, and put a stop to it. Good for you!
