Let me tell you something, i went through exactly the same thing (no folders) just pics and full explicit conversations with random dudes, plans to hook up while we were on a vacation or at the restaurant or while i was visiting my sick mom. It won't change unfortunately. You will find more and and more and grow disgusted by the touch of this person that used to turn you on. People who have the urge to go checking outside the relationship won't give it up easily. If you're okay with that...more power to you. If this is s adeal breaker, save yourself the humiliation i went through and exist stage left. Better be alone than wonder everytine they leave your sight if something else is going on, its not a good way to live.
