Got a question

So is porn cheating if he does it behind your back after you told him we have boundaries and he broke it I get it’s a addiction but the ladies he’s looking at his blonde and a healthy body weight Am I wrong to feel this way about it he only does it when we don’t do anything. ..

I’m kinda “ eh “ about it but it still hurts me seeing that and I think “ oh I’m not attractive to him anymore “ but he still kisses me hugs me cuddles ect hangs out and talks to his friends saying “ my fiancé “ yada yada he talks about me to everyone . But I’m still pretty sure he might be cheating on me regards to the porn
