I don’t know if she’s happy but living in apartment is not worse than living in a house. It’s just different. Better in some ways or worse in others. Since she has no desire to reconnect with kids she might be enjoying not having a family around. There’s a lot to be said about pleasure living alone. Now crazy woman doesn’t want to see her kids. It seems insane. But there are ton of people who have no interest in their kids and enjoy life free of family burden. It’s not uncommon. Sadly.

She might be unhappy not having someone supporting her financially
