Am I wrong?

Caught My boyfriend of only 1 month snuck to take my phone & snoop through it while he thought I was sleeping but I saw him. I waited until I went home about 30 minuets after I “woke up” and texted him afterwards bc I didn’t know how to bring it up bc he thought he was being slick. Mind you I’ve never done anything for him to even be curious or not trust me. Am I wrong for being completely pissed? Is it just me or do you not go through someone’s phone, just an invasion of privacy to me. Had he asked me whatever he wanted to know i would’ve answered anything
