What should I do about my mom?

I recently after 8 years started talking to my mom again. We had a disagreement and wasnt a good relationship and i ended it. Just recently i started talking to her again. Even went to visit her and my sister. While down there, she was so petty. Treated everyone like crap. After everything they had done for her, it broke my heart. My sister and me are wondering should we call her out on her behavior? or just deal with it. Also, next summer we are planning a family vacay should we involve her knowing she want change or just tell to stay at home cause she cant treat everyone the same.
