What I don't understand about all this is the worrying possibility of the wife taking the British born children back to the Philippines.
Can a wife take them out of the country and, apart from the husband hiding the kids passports, how can he make sure the kids will remain in the UK?
Gwapito's marriage seems completely over but if she has ILR and a British passport she will be able to leave with them and come back whenever she wants.
He will lose out as he will not see the kids for a long time.
