ok so, I love my grandma and I know she loves me but when she gets hungry or hyper she gets really rude. sometimes she doesn't realize it but today she went over the top. I am pregnant and no longer with the father ( he wasn't supportive of me keeping the baby) but I talk to his mom all the time. she is very supportive. my gma doesn't like her, and I can to some extent understand that but every time she comes up in conversation my gma says something negative. she has said that Kelly will try to take the baby and things like that. every time she does this I say something and usually she apologizes but she makes comments about anyone she doesn't like. tonight she saw a pic of Kelly and I at my baby shower and made a comment about her weight ( she is a little overweight) I immediately pointed out that it was rude but she just brushed me off. a minute later my mom told her she needed to apologize and she said "what?" then changed the subject. I've called her out on her behavior so many times but she seems to be getting worse. it's embarrassing and I almost don't want to be around her, especially if she won't even acknowledge the fact that she was rude. does anyone else know someone with this problem? what should I do?
