If I can add one more thing to what Leanan and Dianne said, it isn't only the physical abuse, it is the emotional abuse as well. Those under the influence of either alcohol, or drugs, aren't themselves. They are trying to hide from something if it has reached the point of abuse. The Emotional abuse is sometimes much worse, and can leave you, and possibly your young ones scarred. How many days do you walk on egg shells, not knowing what to expect? How many times have abusive comments been made? It is a cycle, which sad to say, may be repeated. Will your daughters think that this type of relationship is okay? Or will they have the strength to say this isn't right, and not include it in their life?
I'll be praying for you, and your husband for healing. Healing of his need for whatever he is getting out of this, and a recognition of his problem. Praying for healing for you and your family such that you don't think this is normal.
Blessings to you today ..
Yesterday is but a dream, tomorrow only a vision. Today, well lived, makes every yesterday a dream of happiness, and every tomorrow a vision of hope.
