Hoping,
I can so identify with your situation with your DH. (Can we change that to mean 'damned husband'?

) I was married for 32 years to a man everyone thought was this great, funny, personable guy. He was a huge manipulator. Negative to the extreme. Moody. Insisted I be a 'stay at home' mom, but had no motivation or ambition to actually earn a livable income, so it was always up to me to find ways to earn money from home while appearing to be the 'cared for' at home spouse. When I started becoming very successful, and there was a demand for me to travel and work on the road, he absolutely hated it. Made it as difficult as possible. Quit his job to 'work' for my business (so he could become my 'road crew.') Yeah, right. He drove a wedge between myself and my staff - all good friends who had worked successfully with me for years. He got more and more manipulative and emotionally abusive, and then blamed all our problems on my escalating use of wine. After all, the problem couldn't be HIM now, could it? He was the good guy, I was the alcoholic bitch.
We were building a house, and he threw my money around like water (he really wanted the business to fail so we could go back to where I was at home, and always at his mercy). Let contractors do shoddy work, and then when I blew at them, sided with them and made out like I was just a f'in unreasonable bitch. It got absolutely insane. He had our kids thinking I had gone off the deep end - all except my daughter, who administrated the business and knew he was draining it dry.
The thing with abusers is, they make you think you're the problem, and then convince everyone else that's true as well. The fact that you admitted to having an alcohol problem played right into his hands. Now he's even got everyone wondering if you're the problem, including your counselor, psych, and best friend. It keeps you off balance and confused. The call to rehabs and your psych is classic for a control freak - divide and conquer. I'd take a bet that he called your friend, as well. He's taking away your support system, and getting them into his corner. Now he's got the perfect weapon, and you put it into his hands. The behavior your step-daughter exhibits is typical of that of a child with a controlling parent. . .they do negative things to themselves to show the parent that THEY DO have control, at least of their own bodies. It's something the parent can't control. (BTW, your drinking may be the same thing for you. . .and now guess who just got control of that, or wants to?) The girl needs you to understand this, and to take her side whenever possible. Cover one another's backs against what is probably a common enemy.
You absolutely should not continue therapy with someone who bridged confidentiality. That is the foundation that trust is built upon. You can't afford to be open and forth-coming with someone who will side with a probable abuser, and reveal confidential information with another person, professional or not. I would press charges. (Hey Nick. . .opinion?)
While DH may seem to want to get you 'fixed' in rehab, AA, whatever. . .guess what? I'm betting he'd rather have you in frequent relapse mode, where he's in the driver's seat, than actually
cured of this disease. Heck, he hasn't even read the book - how 'caring' is that?
It might seem I'm presuming a lot based on limited information, but I am highly intuitive - and reading your post was like rerunning a film from the past. What's between the lines is more revealing than what you actually wrote. Your very first order of business is to get back into the driver's seat of your own life, and take control of things. You gotta gut up, GF! Confront your psych. Tell your husband in no uncertain terms that if he doesn't back off, you'll go live somewhere else while you work this thing out for yourself. (And then, if he doesn't back off, get the h*ll out of that toxic environment long enough to get some perspective.) That's what I finally did, and once I saw clearly what had been going on all along, it was very, very easy to end the marriage. (I'm not saying that's what YOU need to do. . .but you may both need counseling from a more objective professional, and you need to see the real picture and not be blinded by the one DH has so carefully painted.)
Good luck, and keep us posted!
