The question I have is whether his children actually know that he is divorced? Or is he? You mention 'his wife', so are they actually separated/divorced? Yes, its very odd and I would be fuming. Once I had calmed down I would talk to him and suggest that they send separate gifts to their children. £30 is really quite a stingy amount for an AC if you can afford more, especially if you are not seeing them for a meal out etc. However how much or how little he sends is up to him.
