24 Mths in..I gotta whole lot of living to do now

[peacetoday]

Maybe its a moment of despair for her : with her threats

maybe she is drunk as you mentioned

Sorry your girls have to be put through this

But they do seem content to let their mom go for now-

and its nice your D wanted your new GF to be included on her special day

You may hear from XW on and off for some time to come and unfortunately there is no easy answer

either XW will step up to the plate and realize the truth and what she has created or she will continue on this way many years and perhaps get worse into addiction
nothing you can do except what you are doing and moving forward with your life letting her deal with her choices
