Is a son considered disobedient to his father if he prevents him from interacting with his wife when the father's behavior towards her becomes inappropriate, even if the father gets angry about it?

If the matter is as mentioned, concerning kindness and respect, then there is no harm in secluding the wife from the man due to suspicion, provided he is conciliated and appeased. It is necessary to continue keeping the wife away from him and not allow him to be alone with her, in order to avoid temptation. He should be gently advised about the impermissibility of such actions, and it is preferable for someone else to undertake this task.
