*UPDATE* I went snooping 😕

I did something I shouldn’t have done, when I came home from my graveyard shift this morning my bf was dead asleep all tangled up in his headphones so I took the headphones off and put his phone on the charger, when I got curious and unlocked it and started looking through it. I feel really guilty and i’ve never been the girl to do that kind of thing but I found something I didn’t like. Now so you guys understand better my bf had a girlfriend allll through high school and they broke up right after he graduated and then he moved away for college, that was almost 3 years ago. he told me she tried to hit him up once right before we got together last april but he turned her down. now what I found was lots and lots of text messages between them right before I met him. he was still calling her babe, talking about how much he misses her, dirty talking, saying how excited he was to see her when he goes home for the summer. now we were not together at the time so it’s not that i’m upset he was talking to her, I just don’t understand why he lied to me... he told me he hadn’t spoken to her in a very very long time but clearly that’s not true because literally days before I met him he was telling her how sexy she is and all that. why did he lieee?! I want to talk to him about it but idk what to say, I went snooping when I shouldn’t have and he might be upset. I just don’t know what to do.

*UPDATE*

thank you all for your advice and your input, I decided I needed to tell him what I did. I told him I looked through his phone, that I don’t know why I did it and I promised it won’t happen again. I did not plan on mentioning what I found but he asked me “what were you looking for? did you find something you didn’t like?” and so I told him. He says he did not lie as he briefly dated a girl with the same name as his long time ex right before he and I got together. He showed me proof. I asked why he was telling her that he loved her and things like that if she was just a little fling and he said he was being an ass and was just telling her what she wanted to hear... which was strange cause it just doesn’t sound like him but I chose not to question it because he’s always been good to me and hasn’t spoken to her or any other girls since we got together. He told me that he’s hurt that I felt the need to be sneaky and that I could have asked and he would have let me look, I apologized profusely and he said it’s okay but he needs a little bit of time to really get over it. I broke his trust and that was wrong and i’m glad I chose to bring it up and apologize because the guilt would have eaten me alive.

side note: he has mentioned this girl before but I forgot about her, he wasn’t hiding anything from me he had just never told me that he dropped her for me. I thought he dated her quite a while ago but I was wrong.
