I would try to find out why she doesn't want to show him affection. true, there are developmental phases but I wouldn't just chalk it up to that unless I was sure. maybe try playing a game and getting her distracted then slip in a question or two about daddy, kids are more prone to open up if they don't realize they are doing it. it could be as simple as a beard or mustache or even a cologne he uses. as a father and a committer of the "not being around" sin, I can tell you, it does cause issues down the road. I now have a 21 yo and a 14 yo both boys, I have great realtionship with them NOW, but have had to work hard for it. if he loves her, and I'm sure he does, he won't get offended and defensive, if you don't start out that way. just be sure he can ******** down the road a few years and how he wants their relationship to be, say around the time of her wedding. it won't be as far away as either of you think.
