I could write an essay here. and am indeed tempted to. Short answer though is YES!
Women expect too much of men, just as men expect too much of women.
I am not talking the piddling stuff - "Take out the trash, wash the dishes for once, stop using my razor, socks are not a Christmas present" sort of thing. i am talking this crap about "He completes me, or I can't live without him."
You are a complete person in your own right. You need completing by a guy no more that the Met needs a one man band playing a tin whistle. He is too, and you had best remember that.
The image of the handsome prince sweeping you off your feet and you living happily ever after is a powerful one. The handsome prince has a castle full of servants to do his and your bidding. Your prince has himself and you.
A relationship, to be successful, must be between equals and conducted with respect on both sides. He isn't your servant. Stop treating him as such. You are not his servant. Don't let him treat you as such.
You are partners.
There is a huge difference between holding someone's hand to get over the rough patches in life and relying on them to carry you over those same rough patches. The first is a partnership between equals, holding each other up. The second diminishes both of you terribly. You because you are not working to your full potential, him because, well, most guys are simply not that strong in the long term.
You can flip the genders and the exact same thing still applies.
Sorry if this rambles slightly - I am somewhat tired.
