I am a recovering alcoholic who did the same thing, I got sober, my ex did not.
Same here.
My x told me after I got sole custody, "You can't afford to fight me for her the rest of your life".
Scared the crap outta me at the time. It's been 3 years now and she still hasn't bothered to get a job, still drinking, and fortunately for me....not so much for DD, has pretty much lost interest in anything not related to drinking.
LMC (Little Miss Coyote) was just down there for a week and her mom came around for 1 visit for about an hour. Oh well.
Thanks and God bless us all,
Coyote
