Hello justbreathe,
I'm happy to hear that you have been enjoying your time with your husband. If your life with him as it is now, as he is now, is working for you, then that is the most important thing. No one else can live your life or make your decisions.
The only person who needs to acknowledge that what he is doing is contributing to an improvement in your relationship with him is you.
If the situation with your husband works for you, then you need not try to convince the rest of us. As another mod here says "what other people think of me is none of my business". The world does not have to agree with you for you to be comfortable and happy with your choice.
I do hope for his own sake that your husband will soon reach his own turning point, as you have, and want to live a sober life. Many prayers for you both.
