Do you consider porn cheating?

I may be hormonal, I’m 32 weeks pregnant but I found my husbands been watching porn while I work nights and I’m really hurt by it. We’ve been together 12/13 years and he cheated on me about 10 years ago and I’ve been pretty insecure in the bedroom ever since. He’s always telling me how awkward I am and just overall speaks negatively about having sex with me. Which over the years has caused me to not want to have sex with him. I’m usually in my head about it and am definitely a lights off, under the covers, him on top type of girl. That way I’m not in control and he can’t really say anything. Well the other night my phone was dead and I used his to Google something, in his search history was an onlyfans account, pornhub, and another website called chatsturbate. His Instagram and tiktok are filled with those types of accounts with girls in lingerie dancing whatever. And I just feel like him getting sexual gratification from looking at other women is cheating and I’m really hurt. What is your opinion?
