I do agree that the healthiest, most positive thing to do here is encourage the husband/father to attend his daughter's wedding cheerfully and show her love and support. Many writers are jumping to the conclusion that this father abandoned his children. There is nothing in the letter to support this. It is equally possible that he attempted to remain a loving presence in the lives of his children. We have no real idea. What is most significant (and sad) is that, five years later, the father cannot be referred to by name and his second wife is still "the whore." This reeks of children harboring unhealthy bile-filled rage. Maybe the daughter has had counseling and is attempting to overcome it. The infdelity and divorce were between adults. It's sad that it devastates the children and it's wrong. However, justifying the continued rage does not help the children heal. Neither will having this couple stoned by an angry mob.
