Need help or words that could comfort

So lately I've been dealing with sm stress and sadness because of my parents continuously fighting so much because of my dad's mother(my grandma) and my dad not caring abt my mother and not being considerate of her all it genuinely hurts coz he doesn't even realize what he's doing wrong and think he's doing everything right and says my mom is over reacting my parents have been married for 21 years it genuinely hurts me seeing they r still the same as they were in our childhood the fighting is not ending I really don't know what to do my dad acts so Islamic but he forgets how Hazrat Muhammad (SAW) Treated his wives, he completely ignores how my mom feels and my siblings and I feel he only cares abt his mom, it's to the point that mom is talking abt divorce now and I see her crying half the time I see her she has always been so patient but she is losing her patience now idk how to deal with this I feel so bad for my 10yo brother that he has to go thru this asw he's so too young for this
