I don't think that Annabeth relys on Percy that much, instead I think that she knows deep down that she would probably die on her solo quest and just wanted him to be with her. I think because of the falling out with her mother she became more doubtful of her skill which then led her to use Percy as support more than she did in the old books. I mean she has been through a lot and sometimes you just want to lean on someone for awhile.
