What are the rights of the wife and children (a 3-year-old and another expected child) if the husband seeks divorce due to the wife's actions towards his family?

Problems between a wife and her husband's family are common, and the husband's wisdom is essential to resolve them. He must give each party their due, foster harmony between them, and he is permitted to use equivocation or even lie for the sake of reconciliation. The wife should refrain from slandering her husband's family, and she is not allowed to prevent her husband from taking their son to his family. As for a promise, it is obligatory to fulfill it legally if it entails the promised party incurring an expense, unless there is an excuse. A father's gift to one of his children without the others is not permissible unless there is a valid reason. In this case, the need is met by gifting a usufruct (like housing) without transferring ownership of the property. Divorce is permissible when there is a need, but it is preferable to attempt reconciliation before resorting to it.
