Fiancé still talking to his ex
My fiancé and I have been together for over two years. I thought everything was going well with our relationship up until a few days ago. He was asleep on the couch and he got a text message. I checked it, it was a random forward from one of his friends. Then, and I don't really know why, I looked through his phone for the first time ever. There was a text message that he had sent to his ex, whom he had once told me was the only girl besides me that he ever had a crush on and was his first true love. The text message read, "You better do as I say haha." There were no other text messages between them although this was obviously a continuation of a conversation, so Im guessing he erased them which bothers me more than him just talking to her. I don't know what to do, we decided over a year ago to stop talking to our exes because it caused too much drama and we loved each other. I gave up a great friendship with my ex boyfriend because we both agreed that talking to exes was disrespectful. I now feel that he is lying and hiding things from me. I feel hurt and I am not sure if I feel the same way about him because he is not the man that I thought he was. I want to confront him about it, but how should I go about doing it? And why would he do this behind my back when we have a great friendship and relationship?
