Hi and Welcome,
I do not believe that you should push him, nor can you. He will need to come to the decision to seek help for himself. In my opinion, you cannot urge your husband to keep pace with you as you recover. You can show him, but the way you live your life, that recovery is wonderful.
It can be very difficult for couples to deal with growth. In my case, I began drinking after 25 years of marriage and my husband never drank. When I began recovery, I knew instinctively that it was going to rock the boat. But, I had to do it, I had to grow and move forward. I am now much less dependent upon my husband and I am also more tolerant. We are not on the same spiritual journey, but that's okay.
And I dont know what the future is holding in store
I dont know where Im going, Im not sure where I've been
There's a spirit that guides me, a light that shines for me
My life is worth the living, I dont need to see the end.
