How incredibly sad for you. Have you thought that if he has nothing to lose he may not need to change? I know that with all addictions, until they hit rock bottom, there is no real urge to change the behavior. As sick as it sounds, you have the addiction to him as well. We, as women, are so nurturing that we feel like we are incredibly noble staying even when the going gets tough. you and your children deserve the man that you married and the man that he can be..a sober husband and father.
Seek our help from those that love him. work out a workable alternative for him, like inpatient care. This will give him the time apart from you and tell him that it is this or you will have to make other arrangements for him. Don't wait until he is so depressed for the state that he has your family in..you are the hero here. Salvage what you have as a family and re-group and save it. If he can't be on board then he can only be part of your family when he is...this is loving , really. you have to love ALL of you first, and show him that you want more...good luck to you and seek out an alanon meeting quickly. they will have far more answers for you and Gamblers anonymous may have some helpful tips or avenues..
