I'm a bit of both. I love my wife and daughter absolutely unreservedly, but my own family I'm very indifferent about. We don't see each very often at all, have nothing in common and when are in each others company it's very difficult.
It's a horrible thing to say but I've completely out grown them in ambition and ultimately achievement which has led to a lot of resentment on their side.
Hay ho - I don't lose any sleep over it; it's just the way it is.
