<human>: We have been dating for a year and a half and overall have an amazing relationship. It has been long distance for most of the time so that puts extra stress on things. Last fall I was texting myself a picture from his phone and because the iphone shows the last text sent or received I saw a text from a girl he had done a summer internship with that said something along the lines of "I'm glad you're happy / I want you to be happy, I love you." Since I felt like our relationship was really solid and I didn't want to seem crazy I never brought it up. 

Between then and now I learned that they spent the whole year studying together and that during their internship they may have almost (his story has changed saying they accidentally did or almost did) kiss when they were out with people from work cause she tried to kiss him on the cheek and he turned his head. She would also write joking (I think) things on his fb during the internship about him writing her love notes. She is now dating one of the members of their study group and after graduation I don't think they have really kept in touch besides the group chat their study group has (she is the only one of them still in school so they help her with things). She was also at his graduation and he couldn't stop talking about her to his family - telling them how she was a model and won beauty pageants etc. 

I was upset when he told me about the kiss but he showed me all their texts (skimmed) and asked if I wanted to read them but again I didn't want to seem crazy or controlling so I didn't. 

Recently he mentioned he talked to her over the phone and I started getting paranoid all over again. Not that something was going on now but that there had been something in the past. I feel like I'm going crazy thinking about it and want to ask him about the i love you text but at the same time that might be a little insane. I'm not sure if I'm paranoid and should just forget about it, or if I should try to bring it up?

Can you give me a shortened version of the text?
<bot>: paranoid about bf's past with another girl due to accidentally seeing a text saying "i'm happy for you I love you" over a year ago. Should I bring it up or get over it?
