Find the best financial services for you at: SMARTFINANCESOLUTIONS.NET - Help! my dad is angry? - today me and my sister was having a talk. Then my dad just stormed in and started yelling at us.
He did this multiple times before so bad, that I had to call the cops 5 times. Recently he got into a fight with my grandpa- which was very disrespectful since my grandpa pays for everything (buys us food and let us live in his house.) Also he got into an argument with my mom cause we are going through bankruptcy, and he blames everything on her. when he is the one causing all the problems. He even said he was going to hit her.

I told my mom to get a divorce. Basically everyone in my family said to my mom to divorce him.

Every time we try to express our feelings and such, he gets mad and throws stuff and etc.

I'm the only one that can stand up to him. My mom and sister is always just holding it in so nothing worse happens.

I'm tired of my dad thinking he is the king of the world. How can he be so disrespectful to my grandpa, if my grandpa is the one that is paying for the house we live in.

Should I write my dad a letter or something. -I did do that before but he crumpled it up and said gtfo.

he is nice but his anger gets in the way sometimes.

Thank you. I really appreciate it if you give me advice. and ty if you read all of this. -
