You would probably do well to read and share in the Family and Friends of Alcoholics forum too. Unfortunately there really isn't much you can do to "fix" your wife's alcoholism unless she is ready and willing to get better on her own. What's best is for you to take care of yourself and your son as you may not be able to count on her to do so unfortunately.
Thank you Scott, for your advice and gentle nudges to the "right" place. Seems I am a little lost here, as I thought I posted this under "family and friends". Forums are new to me - should I be posting somewhere else?
