I hope you can reframe your thinking to consider previous attempts to get sober as learning experiences rather than failures. Most people I know have multiples slips and slides along the way, and I think that those who are most successful were those who were able to learn from them. Telling your husband and your doctor marked significant steps: You've put into place some supports and some ways to hold yourself accountable.
Rehab was a good experience for me, although I had no spouse or children to leave behind. I needed to get out of my environment and to be "confined" for a little while. I learned a lot about alcoholism---MY alcoholism, to be exact-- and I was introduced to AA--where I had vowed I would never go! It proved to be just the think to help me learn to live sober. And I have lived sober for a very long time. My best to you, and I hope you will stick around here, too. I think that on-line support is a wonderful thing.
