Hi, I am sorry about what you are going through. This really depends on your marriage as a whole and how willing he is to get treatment as well as how effective the treatment is. I think the good first step is that he is admitting his problem and seeking help. This is sometimes the biggest challenge ever. Even if this treatment was not successful it may be good to seek another. It is not impossible to get helped from this. If you are willing to be patient and help him get through this and he is willing to continue with treatment then the chances of saving your marriage is good. This being said given that your relationship as a whole is rather good since other issues can come into play as well. I wish you gentle wishes with this and hope he continues working on this issues. Please let me know if I can be of further help.
