So why not be the person who tells her? About your addiction, about your past or your ED. I am not certain if the delusional aspects of addiction lead addicts to believe this won’t occur, but it does and it will. Addicts think they have covered their tracks that there is no evidence, but there always is and a betrayed woman does better investigation that the CIA. It may not be now, it may be years from now but your behavior every last dirty secret will be revealed to her. So why not just tell her?
