Dear Diana,

My husband's sexual hang-ups stem from his addiction to adult pornography websites. He has not been able to give up his addictions in favour of having a normal sex life with me, claiming that I am not exciting in bed because I refuse to do what these women do in the movies.

This has actually been going on for the past 12 years. He has finally agreed to get help and format the hard disk that contains his porn. My question is, should I hound him about what he had promised to do, or should I see if his words actually translate into action? He openly admitted to me that he knows that he is sick and that he needs help. I just hope that once the hard drive is formatted, he doesn't go back to porn again. Should I up and leave this marriage over this issue despite our 12 years together?
