why do women

Why do women ask and hope for a man that wants to make her happy in everyway. Why is it that they push them away. They hope for a change with in the man there with but know deep down they cant. That's when they decide that its how life is and just go on letting there self being put in a situation where they don't know how to get out of. But that's where my question come's in. If a real man steps in and up too bat they find a way to match the old with the new. I just want to know why.
