Husband and porn

This is humiliating for me and I’m not sure if I’m in the right or if I’m exaggerating. My husband doesn’t seem as interested in sex as I am. We have sex twice a week but it sometimes feels like it’s more out of obligation for him. He gets up at 5 and goes to the gym so he usually wants to sleep early and because we have a o e year old sometimes by the time the baby falls asleep he’s asleep first. I’m really upset because last night he feel asleep literally as my hands were down his pants getting him hard. Today I go with the baby to get groceries and am gone for a few hours. When I get back I look at his phone to play YouTube music for the baby, but what do I see, porn on his search engine. I’m hurt. He’s too tired for sex with me but he can watch porn. We just had a huge argument and instead of admitting he’s wrong he said it’s my fault for grabbing his phone and that just because he watched port didn’t mean he masturbated and that I’m a sex addict whose always wanting it and get mad if we don’t have sex.
