She seems to be judging herself as well and she can see her life has gone downhill a lot and that you may not approve of her or allow her in the lives of the girls
I set a few boundaries when my XH left..I fired him from our business with the help of a L- because he was using and getting high.. I told him them he would have a job if he straightened up- he chose the fast life and left It was for the best for us and our business thrived with him gone if he hits a bottom-- he will sober up- if not, he is no good for anyone including himself he is now D from OW but still deep in addiction
In my opinion, it may be best to let her hit a real bottom if she is using not to help until she is clean- she is telling you- her life is a mess, so we can only guess what she has become unless you want your girls to be around an addict- it may be best to allow her enough space and no reach outs -no help until she is really there and it doesn't sound like she is yet- just a clear boundary, she will only be able to reconnect with her kids when she is clean and sober- just my opinion-
