Congratulations on your happiness, your new life and new outlook!
My AH is mostly a weekend warrior and has had several sober months here and there but only as a dry drunk, never in recovery. He usually just stoped when he really drove me over the edge and did something that was really awful. Then like most dry drunks, he just gradually started drinking again.
At this point I am working on me and if the new me feels I can't live like this anymore, love or no love will not make me stay.
I too have a whole lot to lose, esspecially the love of my life but my sanity id worth more than anything in the world.
Best of luck!
