My opinion is that walking hand-in-hand and being close is something that has nothing to do with the wife's attitude toward him. If it *is* a factor, then the man is creeping toward incestuous attitudes that could be harmful.
There is no such thing as a "standard" father-daughter relationship. My husband and his daughter are very close, for instance, but there is a very clear distinction in our home. There is never confusion about what's "ok" or "not ok." He hugs her and they have important talks, but he doesn't do anything differently than he would if he was unhappy, single, or ... whatever.
Men I have known who molested their children often take great pride in what they perceive to be "closeness." I've seen these guys talk about how their kid talks to them about sexual matters, for instance, but upon further investigation, it's typical that the girl felt interrogated and uncomfortable from the moment he attempted to "get close" in this way.
This question is very disturbing and if you're asking this about a situation you are in, I hope you'll seek a healthier outlet for getting attention and positive regard.
