How do you get to "no doubting"

I am not sure if it is complacency, numbness but I no longer fear him.  I actually feel sorry for him and wish I knew what I could do to help him.

This is an illness, but it is not a illness that is normal.  It is not take two aspirin and call me in the morning or something that a bandage fixes or surgery can remove.

What scares me the most is the future.  Living in a relationship that is less and less something to look forward to.  Living more and more independently as I will not remain at home feeling sorry for myself.  That The joy of Christ is not a common thing we can share. That he can find such horrendous things to say to undermine what Christ does.

Son volunteered at a Christian winter retreat and he obliterated any sense of purity by saying to him he didn't care if he had fun, a good time or got laid, so long as he got enough sleep before he drove home.  (It is a lengthy drive, but that was uncalled for)

A recurring theme so far this year is making the right decision.  What is the right decision.  I said when all this started, that I would not be that woman, 7 years later, tearfully pouring my heart out about what my husband's drinking is doing to me.

Here I am over 7 years later and though I may not be tearful, I am disappointed that I am unable to change things.  Granted I know that God can and I have not been diligent in praying for his hand in all of this, but I have prayed earnestly for Him to heal, to look after him and to make it stop.  I also know that it is God's time and that I am stronger now, but I am actually now reluctant to think about what the next steps might be.

If this is sickness, and the patient refuses treatment, then do I really stay?
If this is no longer the right place, then what is?
Is it a matter of fearing the results of this or fearing making the break?

Even if I tried to seek a separation to force him to get some help, something tells me that it would be the end and he would never forgive me.

James 1:5-6English Standard Version (ESV)

5 If any of you lacks wisdom, let him ask God, who gives generously to all without reproach, and it will be given him. 6 But let him ask in faith, with no doubting, for the one who doubts is like a wave of the sea that is driven and tossed by the wind.
