Just wanted to share a tool with those of you, who like me, felt/feel like you're going mad and going round in circles after discovering your partner had been accessing porn regularly on line. Its a book called 'love you, hate the porn' ( available on Amazon) and is a couples book designed to work through the feelings and emotions attached after such a revelation or discovery.
I haven't finished it yet, but it has been such an absolute godsend to me already, helping me make sense of the negative cycle my relationship has gone through and only wish I had found it sooner. I really did underestimate to power of something like this and for the first time in a long time am starting to feel at peace.
If you're going through a similar battle, then I would very highly recommend it.
