How to get over this?

I need your help. I found some dick pics & vids on my husbands phone in his deleted photos section. I asked him about it & apparently he didn’t send it to anyone. That he was thinking of sending them on onlyfans for a dick rating. Idk, I can’t seem to believe that story. I also saw he made a Venmo transaction of $7. He told me that it was his coworker to spotted him lunch & he sent her the money. I feel like asking him to actually show me that transaction. Also, he looked up a girl on Facebook & I asked him who she was. He said a pornstar. I googled her & she has an onlyfans & does dick ratings. The pics & vids were taken on the 14th & she her last login happened to be that same day too. Seems sus af. This incident happened Saturday night & I just can’t keep beating myself up on this. Me googling the girl happened just now. Is there really a way to get over this?
