Well, if you're content to read the books you already have, then why add the book Willie recommended, to your collection? I know nothing about porn addiction, except that it must be a very tough habit to break. You may want to do some research for yourself on just how many people are actually helped by having an accountability partner. To be fair, until today I haven't seen you post a thread about your porn problem or the need for an accountability partner. So how could Willie have recommended it months ago, when he hasn't been aware of your problem until today?
I think your best accountability partner would be GOD. Not a person who isn't always available when you need them. Like I said before, God is ALWAYS there, no matter what time of day or night.
