<human>: This (Monday) morning I got ready for class like normal and I had slept over my boyfriends house. He was still sleeping and in my bright mind I thought hmm he never lets me see his phone. Before anyone says anything I always let him see mine and if he asks who I am texting I tell. I trust him. Well did. While he was asleep I saw that he had texted this girl, lets call her Janice. I knew they were friends but from reading the messages I knew this was a bit serious. To give you context they knew each other freshmen year of collage and were in the same dorm.

here is a text from him:"...Like I said you're this beautiful girl that's interesting in so many ways..."

some more "lol"s and "aww thx" later 

Text From Janice: "I loved spending time with you. I had serious mothafuckin feelings for you lol. Hell I was totally willing to lose my virginity to you."

His reply: "Same here! Shit I wish we still spent time together, and I honestly think about that a lot (sorry). I still remember all the fun times we had . I didn't know you liked me that much. I always thought I was just a second thought to you.

It seemed like he instigated all of this. 

I took pictures of the texts on my phone and he grabbed my phone and tried to delete them and got violent about. I don't know how to talk to him either cause he argues about it and in my mind he should be groveling. I told him to text her and tell her sorry for saying those things and he didn't mean them and that hes in a relationship. I also told him he had to cut off communication with her like on facebook, snapchat, and texting. I feel like I'll be on high alert every time he picks up his phone and it'll just eat me alive.

What do I say? Should I trust him?

Condense the text into a few key points
<bot>: My boyfriend spilled his feelings through text to a girl he's good friends with. He never lets me see his phone.
