What is the reason a wife does not love her husband's family, and is this behavior on her part normal?

Muslims should live in harmony and affection, and beware of anything that causes disunity. Envy and disputes often arise between a wife and her husband's family due to baseless suspicions. The way to remedy this is to interpret actions favorably, verify information, and not accuse others without clear proof. If there is a strong suspicion of ill intent, then frank discussion and a reminder of the affection and love enjoined by the Sharia are necessary.
