Hi,
Welcome and it sounds like you have a good plan in the works. And, you're right that it isn't easy, but it is very worthwhile. For me, I had to get my depression properly treated in order to stay sober, because without that, I honestly didn't care enough to put the work into it.
As you said, it will be a challenge for you if your husband continues to drink, but right now, just focus on yourself at this time. You will find lots of support here, and I hope you keep reading and posting.
