Does this count as cheating? Pictures included

I was just gonna use his phone to call mine so I could find it. But then I saw he had a snap chat. Which is absolutely something that we're both not aloud to have for obvious reasons. He snap chatted some girl named long haired slutt. That worries me. I'm being induced in two days and then I find this kind of shit....I knew he's been hiding things. He flips out if I barely touch his phone, he hides it when he's asleep, and just plain acts fucking weird about it.
