Dude shouldn't even be mad.
If he got a bullet proof prenuptial then he should just cut his losses.
Sell everything, pack up and move over there and find a better looking filipina. Start all over again. He did it at 55-56. He can do it again at 59-60. Plus it will be cheaper to raise a family with bare help from family and maids, and he can be close to his first two kids.
Life's a bytch man. You got to roll with the punches, and take it on the chin like a champ.
