dear help,
sounds to me like you are doing really good. the appt with the counselor, the attempts to talk to your partner about his drinking...all very good signs that you are not denying reality, your gut, or your responsibility to address your concerns and the problems. not much codependency in that.
what will be helpful is that you learn all the things NOT to do, if you are in relationship with an addict. it gets actually pretty simple, with education and practice.
the world seems to be getting more and more full of people with addictions and it's no failure on your part to happen to have one in your life. so do keep seeking information and trusting your own good sense.
all the best.
