I would strongly recommend both Al-Anon and individual counseling.
EG is right, the
individual counseling with an addiction specialist will be well worth it. You also can ask that counselor what he/she thinks about the efficacy or wisdom of MC during your H's active alcoholic addiction, or early recovery (eventually, I hope)!
Have you participated with your H in MC before? If so, do you have a good history of progress in MC? You said this:
He has a lot of resentment toward me. This is hard for me to hear from him because he minimizes the effect his drinking has had on our relationship and takes little (no?) responsibility for our problems.
The denial, minimizing problems, not taking responsibility, and resentments are all things that I believe an alcoholic must tackle in recovery, and in order to recover. That is the basic work involved AA Steps 1-4 (setting the Higher Power part aside for the moment). That is the business of recovery. It is an inside job that the A must decide to do and actually do for himself. The A, not you. The A, not a MC. The rehab centers assign chemical dependency counselors to the alcoholics and addicts for recovery purposes ... not marriage counselors. That's my experience.
