> I'd love to stop believing in it but it's destroyed a large part of my life.

With all due respect, wouldn't it be more accurate to say that you destroyed a large part of your life? It seems like you're blaming porn, as if everyone who is exposed to it becomes addicted. Is it like heroin? Or is it more like alcohol, where many people consume it without becoming addicted, but a few people ruin their lives over it?
