I need help!

Hi don't know if I'm an unusual case or not but I'm a 49 year old male who has been married for 22 years. Never had much use for porn until about 2 to 3 years ago. My wife had some medical problems that resulted in her having a decreased sex drive and resulting in only once every several months of having any interest in sex. Being a fairly healthy male(sort of) i missed the sex but more I missed the intimacy with my wife. Not wanting to have an affair I turned to porn looking for a release. At first it wa maybe once a week but it soon escalated into once a day to several times a day and more deviant types of porn just trying to get off. Of course this killed any kind of sex life with my wife, which really hurts her and me. I need to get off this stupid self-destructive cycle and get back to being being my nomal happy self.
