Would you break up?

If your boyfriend of 5 years has been turning down sex for over a month while you have been initiating and he just keeps saying he isn’t in the mood/is tired but while he was showing you pictures in his recently deleted he accidentally swiped too far and there was a porn picture of a woman bending down showing her butthole and he was very apologetic and said he only looks at that when he is really honey, would you break up? It wasn’t a woman he personally knows, it was a pornstar...
