I'm so glad you got to spend time with your grandson. Always remember, you are the positive influence in his little life.
This just had to heartbreaking to hear. I do not believe that she really hates you, I think she hates that you have changed and no longer will rescue her.
I may be wrong but I doubt that she is telling your grandson directly, he is most likely overhearing what she is saying to the boyfriend. She obviously does not care what this little guy hears and that is truly sad.
Yelling at her would only give her ammo to use against you. Your best defense against is to be strong, hold your head high and to not buy into anything she says. Again, she is just angry that you have changed and she can no longer manipulate you. I know it may not feel like it but this is a good thing. YOU have made great progress in detaching from her.
You can do nothing to change your daughter. All you can do is be the best influence you can be to your grandson. I would also suggest that whey you have him make sure to tell him how much you love him and how much you love your daughter.
So Tired, you have come such a long way since you first came here, you are doing really well.
