I know the odds are definitely against addictions in a marriage but IMHO the 2 people involved need to own up to what they have done wrong. If either one isn't 100% truthful and willing to make a change then it will rarely work out. Denial is very powerful and regardless whose to blame if you can't see what you are doing wrong in a relationship then it will be difficult to make progress.
I don't think mine is going to survive. 10 yrs of off and on drinking and the manipulation has killed my love for her. I want nothing to do with my wife because I don't think she truly wants to own her faults.
