Caught my boyfriend in a lie ....

So my boyfriend of 1 going on 2 years now said he was going to the bathroom & he had to take a dump . Btw we are really open to each other about that lol  and we live together . So he takes his phone like he usually would have . Never crossed my mind that he would be watching porno , jacking off while I'm laying in bed waiting for him to come back . I noticed when he came back that he had some cum on his pants . And I said something about it and he was like yeah I was jacking off to you . This kinda upset me cause I'm in the room, the real life me & he wants to jack off to a picture . Well I went to use his phone and I opened the lock screen and he had a porn video pulled up .. All I did was hand it back to him and roll over . He tried to cuddle me and I said don't touch me ... This REALLY hurt .. Ladies please tell me what I should do or if I'm overreacting .. Or what y'all would do in this situation
