Are you having a furkin geeraffe!
This country is toss! Review the websites of any of the daily rags in this country and despair!
Send your missus back for a month and she'll realise what an utter buffoon she is being. If she doesn't change her mind get her seen by a psychiatrist, get power of attorney and don't let her leave! lol
If she does still want to come back, brainwash the little uns that they want to stay with their Dad!
Seriously, she must be absolutely bloody potty to want to come back!
