My boyfriend is clicking on girls onlyfans links on instagram. Good enough reason to breakup??

Weve been together 2 years. And its been rocky. Hes never cheated or anything and doesnt follow any provocative accounts however last week i caught a deleted porn screenshot on his phone and hes been clicking MULTIPLE women’s raunchy links??? Yet he barely kisses me lately and we never have sex anymore. Whenever i kiss him he atops it. Im tired of it, i know i deserve more and im ready for better. Kind of want to use this to pull the plug. I would never authentically happily be with a man who is curious about other women no matter if he claims he isnt. And then wont even touch me or kiss me. Like no. I just cant anymore. Tired of the disappointments.
