Its not exclusively the reason, agreed. and to say as a broad generalization that these are the reasons any single older girl is not married is 100% unfair and wrong. Cant blame the girl who’s only been suggested 4 dates in 2 yrs! And yes, there has to be a compatability and comfort beyond the ‘list’. But a lot can be built after marriage through work and stretching. But these reasons still are the case often.
whaleboy- Its a personality and not neccesarily a bad one. I’ve had and heard the same story but almost exclusively with reversed roles, with the boy being shy at first and the girls dismissing them as too quiet.
