wanttobehealthy, what you're describing is my biggest fear. I have no idea of this will last. I'm sure as time goes on and the memory of the arrest is more remote, it will not be as big of a motivator.
May I ask what contact, if any, your ex has with your daughters and how you make that work? My husband is a good, involved father in many ways, although I do worry about the effect of the drinking on my son. He has never been physically abusive, but there have been some episodes of anger that have scared me. Alcoholism runs in both my and my husband's families, so I have to be concerned about the genetic component in my son as well.
