And there we have one aspect of how BBV (Bed Before Vows) can compromise a marriage, particularly when prior partners are part of the equation. Virgins can't compare their current partner to past partners and find them coming up short which can cause feeling of dissatisfaction that may be difficult or impossible to address with the person they finally took vows with.
That said, she was just cruel. That's just not a nice thing to do to a man 😅.
