The use of 'his' here is pretty suspicious. The original story says 'the' kids. We don't know whether they're her kids from another relationship, kids they had together, or his kids from a previous relationship. They could be adopted. But NATURALLY, they're his kids because it was unspecified and you identify with the father, and because them being his kids makes her a bitch. Now it's internally consistent!
