Wrong in many ways, but the simplest one is that you vastly underestimate the huge variety of different behaviors and psychologies of individual human beings, men and women, much less those of the possible types of relationships between them. You have made a very common but extremely limiting error in trying to understand the complexities of life in the real world involving real people. Namely, you are trying to force everything into (i.e., understand everything via) a single simple model or concept and just ignoring all the many exceptions.
What you say above may be true of some relationship, possibly even of all those in which you have been involved (try to realize that only certain sorts of women will find you appealing and that you have zero relationship experience with those who do not) , but it simply isn't true, not even roughly true, of many others. I have observed many exceptions in relationships that have already lasted decades and been personally involved in some.
Open your eyes and mind to what the world presents to you rather than trying to insist on it following some simplistic idea you have that imagines that everyone reacts the same way to the same situations.
Let me give you one concrete example of a type of exception to your notions as described in the above quote: There are quite a lot of women who basically desire to be a metaphorical mother to their mates; they want the love they receive to be like the love a child for its mother...one which is need based. If they don't see, feel and hear that sort of need in their mate, they quickly lose interest. Fortunately there are men who desire metaphorical mothers to take care of them in their mates. It is a good thing when these sorts find each other, obviously. But the point is that the world is full of working and fulfilling relationships that work with a dynamic just the opposite of the one you describe above.
There are lots of other types of relationships that don't fit your conception too; that is just one example.
Clear?
