cheating husband

Aminda

so i was in the middle if getting ready to reset my husbands old phone so i could use it since mine is crapping out. i clicked on the gallery because he thought he lost our disney photos from the last trip. it wasn't reset so they were on there. anyways, i saw a pic on the downloads folder of some chicks boobs so i clicked the folder. there are multiple pics of this girl plus porn videos. i don't care about the videos though. from there that made me look through the rest of the phone. i found multiple different numbers some sounded like hookers. only 1 number was saved. the girl who sent the pics. out of all of these different messages it doesn't sound like he actually met up with anyone but apparently he was friends with the girl before he met me (i hope). i consider this cheating even though it doesn't sound like he met anyone. he's out of town this week for work so i can't say anything to him until he gets back because now it makes me wonder what's on his current phone. he's never seemed like the type to do this. i don't know what I'm gonna do if there are current messages on his phone. any advice??
