This morning I went to CVS and my bf made me take his phone bc mine isn't working. I opened his phone to pull up Spotify in the car and it was already on his Twitter messages.  Now, I never ever ever read his stuff and I have really good self control (usually) about not even scrolling through to see who the messages are from even tho my brain is always telling me to, I know I shouldn't.  

Well today I fucked up and scrolled through who had been messaging him (I never opened any of the messages). But I happened to notice he deleted messages from one girl in particular, a girl that he had been talking to while he was talking to me.  A girl that used to be my best friend in high school. A girl that I still feel insecure about and has made me feel disrespected and made me feel like my relationship is a joke to her.  
I don't know why he would delete the messages when he knows I never read his stuff (normally) and he always tells me how much he trusts me to not go through his stuff (even though he has gone through mine in the past). 

I rationally don't think he's hiding anything from me.  I really do trust him.  I just hurt myself and I don't know how to make the other negative thoughts stop.  The other part of my brain is just telling me to run and end this before things get worse.  Please someone help.
