I don't think that there's anything there to respond to. She's just used to talking to you about this stuff and you're not there anymore. But, she chose the situation so let her be.
One thing though...you have younger kids. Is she thinking of going without a home phone? I insisted on keeping a home phone while the kids were younger and had no cell phones. There will be times when they might be at home alone for an hour or two. They need a way to call if there is an emergency. Also, it keeps you from having to call her to speak to your children. Just food for thought.
