you were out of line by even playing along with the ex. As someone said, why didn't you tell him to pound dirt after the 1st text. You were out of line. You can fix this, but it's on you. You need to stop trying to make him the bad guy. He looked at your phone. Not a. Most couples share phones. I think secrets in a relationship are dangerous anyway because usually if you feel you need to keep it a secret ..you shouldn't be doing it anyway. Where he keeps his phone is beside the point and it's bad form to try and cast doubt on him when you are in the wrong here. Unless you sincerely believe that he is being in some way unfaitful to you, but as such, you have not indicated that. What exactly did you come here for? Absolution? To be told that he was wrong and a snoop and that you did nothing wrong? I find his sin in this to be much less than yours. He looked at a phone, he didn't crack your etc. You were wrong, but you can fix it. Its much on you at this point.
