You are beyond the last straw and done working with him, so at this point it's just the waiting game until you are ready to end it. I don't check through phones etc. but sometimes when I Google something on my bf's computer his autofill will pull up some stuff. I don't go to the sites, but I ask him about it, usually jokingly so he'll blush. So, my vote is say, "I saw some stuff in your phone about blanking all kinds of people and then spy cams, are you going to start a movie production company?" If he acts concerned about your actions, say, "Well, you do all kinds of stuff I am concerned about and it never stops you. How does the medicine taste?"
