Was looking through my husband's pictures on his phone last night and found 2 pictures that were screenshots of escorts in our area in his phone gallery, like he had went to a webpage and screenshot them.. how would you handle this situation? We've been married almost 8 years and have 2 children.

UPDATE: I confronted my husband about the pictures and he said somehow the escort agency got his number and he was getting calls from the escorts saying they were looking for new clients. He said he saved the pictures for the phone number on them so he could Google the phone number and then block it. The thing is, the pictures don't have their phone number on them. They're literally just pictures of the women half naked.. I'm so confused and not sure what to do or how to approach this any further as I have no other proof that's he's doing anything other than the pictures.
