Should i divorce him for masturbating to porn?

Ive been w him for 8yrs, and theres always been an issue w his porn use. I feel like its cheating to me.

Last year, he suggested he watch porn while we have sex, and he tells me it doesnt mean he loves me less, theres jyst always someone whos more attractive than i am. I decided to give it a try for a few weeks, it hurted a lot, so hes stopped.

This time, there will be days where he cannot ejagulate while we are at it. He will get frustrated, stop having sex w me, and masturbate to porn instead. He doesnt care if it hurts me.

He tells me its just a quick chemistry, it doesnt change how he feels about me, he tells me porn is beneficial to men cause it helps them to not cheat when they cant have sex w their wife. And he says it doesnt mean hes into those women. And he says with the busyness of our life with the kids, he needs it

I feel like i should divorce him for this.
