Shell, I have followed your story, but the lines are blurring with another member. Has your wife gone to treatment at all in the past? Generally, ANY history of alcohol/drug abuse, whether the law was involved or not, gives the other parent a huge favor in the court. What about bank statements? I had months and months of statements that had check copies to liquor stores, daily, sometimes more than once per day. It's like he was hosting a party......who can spend that much on booze. Yikes.
Good luck, sounds like you are doing the right thing.
