Re: the preacher re-marrying -- yes, I see both sides of this issue -- as you said blessed, a case like that would be awful on the family/children left behind and forgiveness would be VERY difficult to ever give to a cheating father (or mother) in that situation.
OTOH -- as Harriet said, this is a situation where I am sure many prayers have been said... and you know, LadyM, I wouldn't be surprised if the deceased spouse told him the same thing. She would have known very well, better than anyone, how much he relied on her and how much he needed her in his private life and his ministry... so if he could find someone who could share that load with him, his first wife would probably be praying that God would send this person to him.
My aunt is upset; she thinks it's awful. (He is expected to remarry approx. 1 year after the first wife's death.)
My mom takes the other side; she says the second wife will have big shoes to fill, but she can understand his need for someone to help carry the load.
My mom has also said before, like you, LadyM, that if a person is absolutely opposed to remarriage, that the first marriage must not have been all that great. But if someone is eager to remarry after the loss of a spouse, then that lets us know that the first marriage was a success and the widow/widower hopes to repeat what was a source of happiness.
