"I agree. I do not say anything because I have tried to stay out of ahs recovery"
Your husband is not in recovery, he is still in the throws of addiction, he is drinking. Not letting your neighbor in, basically has nothing to do with whether your husband drinks or not, he is drinking because that's what alcoholics do. Drink.
If you do not want the neighbor to keep banging on the door, tell him so, if he persists, call the police. I assume that this is the same guy that you had issues with before and didn't call the police on, nothing has changed.
I hope that you do leave and stay away until your husband is actually in recovery and not drinking...for a long period of time. Your children deserve so much better, this enviornment is not healthy for them. If you can't do it for you, do it for the innocent victims...the children.
