You sometimes have to walk away from the person who is sick when they don't want the help. This person knows that if he tells you the same sad story you will stick around. You are showing the partner that YOU MEAN IT this time. Tough Love. It hurts but in the long run either he will snap and try to get help and this will be better for the both of you or he won't and YOU will know that he just isn't going to change. You deserve a good life, and you are taking the first step in pursuing change and a better life. Good luck to you. Everything will be allright.Hugs to you.
