movie moment – real?!

so i just saw a movie and there the woman was telling her husband
“i need you to know that you are the man i want to want”
so i guess my question is in our scs world that doesn’t exist right?
i mean if she wants it she can want him.
there is no scenario where someone has to break up because lack of feelings. Because we generate our feelings.

like she is leaving the husband because of the lacks of feelings.

is that right?

thanks so much!
