TITLE: Me [19F] with my boyfriend [22M] of 5 months having issues cause he won't stop texting this girl.
POST: Okay first. I'm not a very jealous person. But when it comes to this kind of stations, I get worried because my SO have left me for a friend who tried to reconnect with them.

I'm not sure that's what's happening here but I confronted my boyfriend about it and he said she's just a friend who they've have had classes together before he met me. I asked him that if she really bugged him, because that's also what he said, he should just stop talking to her. He said that that would be a dick move and that I should think about it like this : If he and I broke up, and he just stopped talking to me, I would be mad at him. No, of course not I would not be mad at him if we broke up and he stopped talking to me because that's usually what happens. But regardless of what I say, he won't stop talking to her, he said he won't start conversation, but he won't ignore her either.

Also, I couldn't help this but I saw the opportunity and I went for it. My boyfriend and I were watching TV a couple of days ago together and his mom called him to help her with something. So when my boyfriend was in the other helping his mom, I saw that he left his phone. I tried looking up their conversation but he had deleted it. Is that sign of something must be wrong? Am I just paranoid? Should I ask what is really going on? I don't want him to think that I don't trust him because I do, but I need to careful that I don't get hurt.
TL;DR: 
My boyfriend won't stop talking to a girl that I asked him to stop talking to. Plus deleted his conversation with her on his phone. Please help
