Should I try cutting off contact with my father?
Are you sure about that? Cutting off contact seems a bit serious.
I don't want him in my life anymore.
It's rude to not talk to a parent. You should try and mend your relationship with him.
I just don't feel like going through all of that trouble. Cutting him off would be easier.
Cutting him off would be easier but it's not about making things easy, it's about trying to do what's right. He's your father and you should want to try to make things right between you, for both of your sakes. You should at least give it a try.
