What is the way to deal with my fiancée who rejects criticism and defends herself excessively, then apologizes later, and will that affect our future dialogue?

If the fiancée is generally religious and of good character, she should not be abandoned due to the appearance of undesirable traits, for perfection is rare. A balance must be struck between virtues and faults, knowing that good manners can be acquired through habituation and practice. It should be noted that the suitor is a stranger to the fiancée before the marriage contract, so it is not permissible to speak to her without need. Moreover, withdrawing from an engagement is permissible but disliked if there is no valid reason.
