I can relate quite a bit, I too had this happen, my husband of three years , we've been together six left me after he went to rehab, said he had to start over again. I have also supported and loved him through all this, even when he came home with his second dui, he may be going to jail. I have been going to alanon and I know I am co-dependent. I still love him very much and want to fix our marriage, but for now he has to learn to deal with his stuff and figure it out. I hope and pray he will, He is a good man he is just an ah. I have been heartbroken over this and am learning to take one day one hour and one minute at a time. He wont go to see a marriage therapist because right now working on him is all he can do. Just know your not alone, there are more of us out there some who want to fix it and some who don't.
