Does he have a problem?

I've been complaining to my husband that we don't have enough sex. He does work a lot and says it's killing his sex drive, but we only have sex once a week, if that. I talked to him about it and found out he has been watching porn & masterbating 2-3 times a week (that he admitted to anyways) behind my back. I had a feeling he was doing that instead of having sex with me but now I feel so hurt. Does it sound like maybe he has a slight porn addiction? I should add that he can barely get hard for me anymore & has been going soft even in the middle of sex 😢
