I see my story in yours. My AH came home from rehab. A few days later, we met up with our friends for a happy hour (it was his decision to go). My AH didn't drink all night. I was very proud of him too. He didn't get involved in a program and 12 days after getting out of rehab, he relapsed. He continued the relapse roller coaster for four more months, each binge sinking getting worse and worse (and each binge promising himself that would be the last). Finally he made the decision to get sober and he has been working his recovery ever since - 35 days sober. I don't mean to be discouraging, but just be prepared. If an A isn't working a program, there is little chance he will stay sober. Support his recovery, but don't lose focus on you.
