Digger, you can't take things like this personally. Little kids go through all sorts of phases mostly designed to help them figure out the world and assert their independence. This sort of thing is one of them, and girls (just in my personal experience - I have one NT daughter and one AS son) will do a lot of pulling away as part of growing up. It isn't about you, it's about them trying to be "big" and "independent." It doesn't mean they don't love you, or that they don't enjoy affection, but that they want to interact on THEIR terms.
Just wait for the first "I hate you" or "you are the worst mom in the whole world" or "I don't love you." They don't really mean any of that, either, just that they don't "feel love and warm fuzzy things at this particular moment because they've mad at you." My response is usually a simple, "I am sorry you are upset with me right now but ..." My daughter will pull off the worst things she can say to me, claim she doesn't need me and never will, storm off into her room, and 15 minutes later cry out "I want my mommy." Of course, your daughter is much more likely to do all this with your wife than with you - it's a mother / daughter thing mostly - but, still, it is something you are probably going to see and will have to stay calm about.
Do you know that the female brain and body is fully grown by age 16, I believe, while for males it is age 25? That means everything is condensed with girls. It all happens at warp speed. And, so, it's going to be more intense. Or, at least, that's one of my current theories.
ANYWAY, don't make a big deal of the hugs and kisses with her. Sit back and wait for her to initiate.
