Put your worries about your husband aside right now... Yes, it looks like he will drink alone... and, it will be up to HIM to get over it.
I have experience with this. I will tell you that it got much better for my wife and I. Things are different. I won't lie... but we are working through it and we are very happy to grow old with each other...
Get yourself recovered. You can't help your husband at the same time.
