@jak
He DECIDED to take the new job to move...NO one forced him to take it .
He said it himself in the previous 2 chapters.
Again, this is not the first time he done this to his family...If you remember early chapters, he has moved his family many times for the sake of his job.
Changes for kids at young age will make it harder for them to get used to environments and friends.
HE IS THE arse here..
At least finally this time, he did the right thing although his childish complaining is very "mature".
