My wife gets agitated and shows rude and aggressive behaviour during her periods. She completely loses sense of what she's saying and becomes emotionally unstable during this time. This behaviour pattern also occurs whenever she's under stress due to work pressure even during her non period days. This behaviour is only directed at me and our only child or her siblings. She never misbehaves with her colleagues or friends or unknown persons. Her irrational behaviour is taking a toll on me personally and our only child.
