When you go this time, don't say nothing to no one ... Just disappear and don't look back.
Once you get settled into a new place, have your name legally changed and move again.
I'm living proof that if you don't want to be found there are things you can do to not be found.
You've got to make sure you are absolutely ready to never have contact with anyone from your past ever again though ... It's the only way - Kinda like your very own Witness Protection Program.
