I know i was in thr wrong but..

My boyfriend never even lets me take selfies on his phone, as soon as I touch it he snatches it off me. I snooped on his phone when he was asleep snd found a few females but friendly conversations which I don't care about but whenever I mention him hating me on his phone he avoids it? If he just said he just doesn't want me on my phone that's cool but I mentioned if he's hiding something and he just avoids it. Did I possibly miss something that he's hiding from me or am I just paranoid?
