As I was reading your request I was realizing that I am a lot like your daughter. I don't have a good realationship with my mom and althought I realize that your situation is different, maybe these tips can help. Don't be pushy. I know that when my mom acts that way I push her further away. Don't be selfish. When my mom calls it is all about her. She doesn't want to talk about me or my kids, just about herself. And be really careful not to bash her dad. Dad's and their daughters have a special relationship and it is hard when the mom's talk bad about them. I think that you should write her a sincere heart felt letter. Let her know how you feel and maybe this would get some kind of reaction out of her. Good luck!
