@Matr0shka Wow, I just saw this. The whole situation sounds toxic. I do not think you should take your mother in under any circumstances. I do not think your grandparents should put up with it. What are the consequences for her behavior? The stealing, lying, chaotic behavior? I think if your grandparents do not set boundaries she will have no reason to change. If you take her in you are signing up for alcoholic misery and I do not believe it is good for you. I personally think she needs to be given the choice: rehab or leaving. She will never change otherwise and she will cause stress no matter where she is.
