Okay! I am a recovered, yes, recovered, alcoholic. I have not had a dring in over 22 years! If you feel like he is your soul mate but can not take anymore, seek a couselor, my husband and I did. It works but the trick is that it has to be a two way street. I decided I did not want to live that way and I saw that I could lose my soul mate so the choice was easy for me. The choice was easy, the cold turkey was not so easy to swallow. But before you throw in the towel, and that is exactly what I think you should do if the children are suffering, offer him an ultimatem. It worked for me but may not for other people. If you feel like you are wasting your time, get out for the childrens sake! I have heard my son say that if I had not quit drinking, he would rather see his father and I get divorced. Remember, it takes some time for the urges to go away, but with family support and a lot of patience, it can happen. For me 22+ years sober and counting! If I can do it, anyone can do it. Unless you are at your wits end, try couseling. I know that sounds cliche but if he is as determined to work this out, it will!
Good luck and remember to always put your babies first. They depend on you! You are their protector and support!
I wish you the best and will put you and your family in my prayers.
