Mark, just a couple of things to add, women get really put out by ex wives and daughters from previous marriages, its like walking on eggshells, plus the fact your wife is Filipino, who can be quite fiery. If she is anything like mine they can find fault in what we would consider the most trivial of things so try not to throw petrol on the fire.
Why don't you make up some reason to take yourself away for a couple of days, on your own, things may well cool down.
