I don't want to be with my dad when he's around
Is there a specific reason for not wanting to be around your father?
He always tells me to do things I don't want to.
I understand that feeling as there have been times when I've struggled to mesh well with my parents. However, I'd encourage you to speak with your father and let him know how you are feeling. He might not be aware of how his actions are effecting you and perhaps he can work on doing better in the future.
My life is going well without him.
That makes sense, but have you considered giving it one more chance? After talking with him things might improve and you could grow to value your relationship with him. If it doesn't work out then you can move on.
