my parents have been married for 21 years now. my dad has always been disrespectful to her . Recently he has been accusing my mom of even smaller things that happened 20 years ago and says unimaginable bad words . he has been accusing my mom of being irresponsible, disrespectful to him and his family even though I know she was never . This continuous outrage has been affecting my family , my brother myself and my mom. Whenever I take a stand , he starts reacting and immediately takes an attempt to leave the house . can someone pls help what should I do as a child in this matter . how should I bring this to an end
