Do you get bothered with your partner watching porn ?

I lived with my boyfriend two years and he never watched it we’ll just in may we had a disagreement and i kicked him out it wasn’t nothing major but we lived with my mom and he says he doesn’t want to go thru that were I feel free to kick him out whenever since it’s my parents house well we are working things out and he’s staying at an rv park I come and stay a few days until we get our town house next week I have nothing against him watching porn since I’m not with him daily but I guess I’m a little butthurt that I found the dvd while cleaning it’s brand new and sealed he hasn’t opened it yet but i felt he was acting shady because theday he bought I called him and he didn’t answer cause he was at the adult store buying it well mind you we have gone to the adult store together he has bought me toys so there’s no need to hide stuff like this he said he wasn’t hiding it from me he was gonna ask me to watch it Friday with him and when I told him I found it he just laughed and I was upset am I over reacting?
