Am I right to feel hurt?

My husband has recently has started paying more attention to his phone. Well he and I usually sext and every time that I would send him pictures or videos his responses would be that of an enthusiastic horn dog but lately his responses have been slim to none and very vague. I wondered what was going on with him so I asked what was going if I was still enough for him if I needed or he wanted me to do other things. He responded that I am enough for him. Well I asked if I could use his phone to look up something he said sure. I opened the internet browser and porn hub was on there. So out of curiosity I asked him how often he watched porn and he said “when you are at work your videos aren’t enough.” I was at first shocked he said that but now I’m definitely hurt.
