Maybe she's getting pressure from her family. You never know what family dynamics can do. I know some people who are just sweet as pie, yet are totally different around their kids. Maybe grandma blames her for the decrease in contact and gets mad when you talk. I know a number of sweet acting grandma's that treated their children like dirt. I would not jump to conclusions. It seems to me she would be trying to be even sweeter, to get back in your good graces now that she is closer.
