When I was 5 my dad cut me with a stanley knife
Are you serious? Why would your dad cut you?
I told him that I wanted to live with mom and he cut me and left me with a scar that is still visible on my left arm.
He shouldn't have physically harmed you. You should report him to the police.
It's fine, I just wanted to say it out loud since I now I can
I'm glad that you've been able to move past it and forgive him for what he did. Hopefully after that incident he stopped doing such terrible things.
