Does it really matter if she likes you because she is genetically or socially preconditioned to think you’re handsome?
Or she is randomly attracted to your pheromones?
Or you randomly share an interest?
Or whatever other random thing causes it?

Or that she likes you because you want her to?
Provided she still is allowed to decide for herself whether she wants to be with you.
Because people can like each other, without wanting to be together for other reasons.

Emotionally I agree that yes it matters, but I find it less easy to argue the point rationally.
