Boyfriend going through my phone

Taylor

So I was at my bfs house and when took a nap but when I woke up I couldn’t find me phone and he had hid it so when I finally got it back I saw I had 1 less Snapchat and it turns out he had read my Snapchat from a guy that I just hadn’t bothered to open cause I don’t talk to him and apparently my bf messaged him and blocked him. My bf and I have been through him going through my phone before and I thought we had settled it and he trusted me. I don’t think he knows I know he went through it but should I bring it up to him? He hasn’t said a single word about it to me
