My daughter did exactly the same thing with my husband. It was because he was never really involved with taking care of her. She did not really start bonding with him until he took an active interest which was when she was around 2. Every once in a while she still says she doesn't love him lol! She was always just so bonded to me. But basically just having him take over duties slowly got her more bonded to him.
