Thank you Dandylion
And thank you Hope4Life and Lexiecat. I know you are right. He is not drinking for now, and I will never allow my children to be around him if/when he drinks again. I know that is one boundary that I will not break, or let him break.
Sometimes I start to forget about how horrible things actually were, now that things are calm, but I do know what he is capable of, and have not forgotten all the horror he put us through. I have an extra car key and a cell phone he doesn't know about, that are hidden, just in case.
