Sorry you are going through all this. I think protecting yourself, insulating yourself from liability, taking away credit cards in your name, or joint, etc. -- that's a very good thing. It's necessary. Mandatory. I did this. Being in the financial field, this is part of what I do professionally with clients when they come to me to discuss divorce, a spouse who has a drinking or drug problem, substance abuse, etc.
However, there is also sometimes a fine line between doing this -- and jumping in the pool with the alcoholic. Going through various exercises, trying to hold them accountable, getting truths, accurate information, rationalizing, budgeting, and all that . . . sometimes all this is enabling. It's part of the 'ism's and the behavior and I don't want to get sucked into all that. Protect myself, yes! Dance and negotiate and all that, no!
Keep working on yourself. All the best.
