I agree, has to be a selfish pursuit, it's that serious (as you already know). She can obviously barely care for herself at this point so no, she has no time (or will) to care for others.
She is well in to addiction and I agree with Dandylion, at this point she probably does consider you to be the enemy - that's unfortunately how addiction can work - try to stand in its way and get mowed over.
There is "sober" which merely means not drinking or using other drugs and there is "recovery" which she is obviously no where near. It means accepting that they have no control over alcohol, that there is work to be done to repair all the damage to themselves (mentally at least) and to others (hopefully make amends somehow). This is far down the road.
Where will she go when she finishes rehab? Are there any sober living facilities perhaps?
These aren't really your concerns anyway, her recovery (or not) is hers, except the where will she go afterward part since you have to live with that. Other than that, your time will be so much better spent focusing on you and your Daughters. Alcoholism affects all of you and has probably been the center of your worlds for quite some time. It doesn't need to be. That can be a hard mindset to get out of, but it can be done and I think you will find when the focus of your family is you and your children, life will be much happier for you.
