Husband and onlyfans

I went on my husbands phone to check how to fry an egg(stupid but whatever) and I saw he had been browsing a chicks onlyfans. When I woke up this morning I had seen his debit card laying out. I don’t know what to do. I wasn’t trying to snoop but if I find it he will just hide things more and make sure to delete them. (Because he feels embarrassed if I see what he’s watched) I am feeling terrible and I have a pit in my stomach. I’m thinking of taking a break but I’m so unsure. Maybe im overreacting but god this hurts.
