Hi Angela,
I can definitely relate to your story. During my slow start on the program, I would ask my husband to support me in it, but he was so skeptical. He had seen me break my promises so many other times in the past (on things that I said would "fix" me and "make me happy"), he just said "I'll know you're serious when I see you do it". Well, that hurt. But in a way I knew it was true. I had to stop talking about it and just do it. But that doesn't mean go all the way, right away. You can only take one step at a time. And even within those steps, take one nano-step at a time.
And I also had to realize that a non-SS person will just never understand what addiction means. They can't seem to fathom that it's not about will power, it's not as easy as waking up one day and deciding you're just going to say "no" to the substance.
I hope that you can find your easiest nano-step to start working on, and just let that be enough for now. We can help you trouble-shoot your road blocks, or you might find one of the Step lists helpful. I also hope that you and your husband can come to an understanding about what healing means. My husband still does not accept all the theories behind what I'm doing or even how slowly I'm going, but he's noticed differences in me so he's starting to have faith and to trust that I know what I'm doing. It took a while for me, but I finally trust what I'm doing, too.
