I would not put my life on hold for 4 years for a man who would trade a good life with a loving woman for 4 years in prison just so he could get wasted.
In a way, codependent partners get wasted, too. They waste their lives waiting for addicts to get their act together. I wasted 25 years of my life waiting for my alcoholic boyfriend to get his act together. And you know what? He NEVER did. He drank himself to death one year ago.
My needs and wants were never at the forefront of his agenda. Drinking was. I would take the 4-year prison term as a gift--one where I could focus on myself and spend some time in a recovery program figuring out why I danced the alcoholic-codie dance in the first place, so I never end up in a similar situation again.
