Was I overreacting?

I fell asleep with my laptop on when I was watching a movie with my boyfriend, I said he could finish the movie and I cuddled up to him to sleep, while I was sleeping my friends texted in the group chat and he read then I have whatsapp connected to my browser, he told me laughing at our conversations he scrolled back and read all of them, I told him that was an invasion if privacy , his defence he read it cause he saw his name, the text was 'she's with 'my boyfriend's name' he had no right to read my messages and now he diesnt want too apologise.

Was I overreacting?
