My family is falling apart..

So tomorrow is mother's day and my brother is going to cut my mom out of his life. He can't take her lies and bullshit anymore and I don't blame him. We have given her every chance, helped her in every way, but she wont change. She is still lying, still spending money, got another credit card, and still puts her church before her children. Maybe this is the wake up call she needs. Im just thankful I still have my brother and my grandparents.
