I used to have a very rich great aunt who didn't have any children to leave her estate to. So, she decided to split her fortune among her sister's grandchildren for them to go to university.  Most of my cousins are about 10 years older than me, so they got their inheritance relatively soon. However, the money for me and my sister (roughly $37 000 USD each) was put into trust for the both of us. 
My parents divorced when I was about 8 years old. My dad has been an alcoholic for as long as I remember and has never considered quitting. To my knowledge, that is one of the things that tore our family apart. 
After the divorce, he would rarely come to see us- only on holidays. My sister has memories of us waiting for him to come pick us up, and never showing up. To me, it just always felt as if he chose the booze over his daughters. 
I was supposed to get the inheritance when I turned 18. I was ready to go to university but couldn't get a hold of the money. He gave me around 5 000 CAD and he said he wanted to give it to us when we turned 21. When I turned 21, I brought it up and he said that he had hit some hard times and there wasn't much left.
I know he makes decent money. He didn't pay child support for us growing up. He now lives in the country and hardly works. I will go to visit him once a year and be amicable, but I can't help but feel like he stole from my future. I am now in university, and have a large student loan and work part time as a waitress to have money to get by.
People say that he is my dad and I only get one dad, but in my opinion, fathers don't steal from their kids. 
Reddit, AITA for cutting my dad out of my life for spending the money in trust for me?
