None of that is bad advice. However speaking to the man, I would say that if he can't manage to talk to her father then he's not ready to lead a woman.
Yes. What is sometimes forgotten, is that when a man marries a woman, he is also marrying her whole family, in a sense, and in a particular way, her father.
The relationship a woman has with her father, will directly impact the relationship she has with her husband.
When the wife perceives that the husband is being “mean” (a problem all too common it seems) she will often flock to daddy to make everything better again, forgetting she is now under the protection and authority of her husband, which her father willingly bestowed upon the husband at the altar.
Of course, the father can help her (if he does not cause division between the spouses through an inordinate attachment to his daughter), but the future husband should be aware of the kind of dynamics he may be entering into.
