Boyfriend watching porn and webcam videos while im asleep in his bed

So I went through my boyfriends phone awhile ago and discovered he watches porn while im asleep in bed next to him. I told him that I dont like that and that he should just wake me up and we can have sex but he still watches it and doesnt wake me up. Also last night I went on his phone and in his recently opened apps there was an app he was using to video chat with random girls and he was messaging girls and showing them his dick. I immediately woke him up and showed him the messages and he was laughing acting like he didnt know what it was then continued to try to lie about it. he eventually told me that he watches these videos sometimes when he doesnt cum when we have sex because usually if I cum before him im tired and dont want to do anything, hes told me that its okay that I dont help him finish but then I go to sleep and he watches porn or talks to girls on webcams. he told me that im basically the reason why he watches it because I dont make him cum sometimes or because I wont wake up when hes horny. should I be upset or mad at him?
