<human>: I have been dating my boyfriend, Jim, for 3 years. We get along very well and I definitely see a future for us. The only problem is I really don't like his family, and more specifically his dad. His family is very neglectful of him and overall treats him very poorly. However, I can endure his mom's side of the family because his grandma and aunt are very sweet people.

His dad, on the other hand, is someone I honestly can't stand. He's been to jail for child abuse (hit his step kid), stole my boyfriend's car ( a whole other issue) and was even abusive toward my boyfriend's mom until they divorced. However, my boyfriend still seems to want his dad somewhat involved in his life (i.e. attend his wedding, going home for holidays). 

My issue is I do not want any involvement with his dad. I don't want him apart of our lives at all. I understand that's completely my decision to make, but if we have kids, I do not want his dad around my kids at all. I know that may sound unreasonable, but he has been to jail for child abuse.

Have any of you ever hated your SO's parents, and how did you deal with it? Also, what would be the best way to bring up this issue with my SO?

Can you give me the gist of the text in a nutshell?
<bot>: I hate my boyfriend's dad and want him out of our lives. What is the best way to bring that up?
