Please help

I need help, I don’t know if I’m crazy or overreacting. So I have found porn on my boyfriends phone multiple times, we have been together for a year and a half now.i always ask him about It and he lies to me every time . He doesn’t know I found It every single time but I don’t appreciate him not telling me the truth. I found It again tonight and It makes me self conscious and upset Bc he doesn’t have sex with me and tells me that’s all I care about but he watches porn every night. And not only does he watch porn I found like chat rooms and stuff with other girls. So can someone help me is it worth being upset about?
