If you're like most women, you probably don't know as much about your dad as you think you do. He can be a mentor, a cheerleader and a friend. But all relationships take work -- especially this one.

Throughout much of history, mothers were the center of a daughter's universe. But as young women join the world their fathers know, it's a whole new age of possibility for a daughter-father relationship.

One of the most painful and confusing passages in the lives of women is when dad is there, but changing. The rock in their lives, who they desperately want to please, is suddenly different -- and so is the bond they shared.

There is a difficult emotional terrain when a father's interest in his daughter's life extends to trying to control it. How does a daughter balance intimacy and independence?

Will a daughter taught to be a hard-charging, take-no prisoners competitor with men have trouble adjusting to the necessary give-and-take with the man with whom she shares a home?

Women who say they hunger for a new intimacy with their fathers often have a hard time defining it, or apportioning it -- how much is too much; how much is not enough?
