Porn amongst other things..

Hey lovelies, I suppose I just want to know if I'm over reacting so here goes.... My partner of 8yrs knows I don't have a problem with PORN aslong as it doesn't become a problem, anyway I've been on his phone and hours at work he's been watching it so we sat down and spoke about it and I explained it shouldn't be something he's doing at work and he laughed it off. A couple months later I'm sorting the kids out/cooking dinner/ cleaning while he sits out the back for hours on my wifi, I see that it started with naked videos, than naked singers/actors and than went to sex videos from 1 town over, nothing came up but it's the fact he looked it up hurts. Am I warranted to feel like this? He flew completely off the handle at me and said that I can't feel upset because 4yrs ago apparently I was flirting with a mate of his when I NEVER WOULD... I don't believe it's the same as porn, these are women I could very well know or walk past in the street, it makes me so uncomfortable. He has apologized but now he has said sorry he expects me to just move on and get over it but so much has been done in the past I don't know if I'm just too tired of his shit tbh...
