My DP left his hard drive at my house before the lockdown, it has movies on it so a couple of nights ago I plugged it into my laptop to watch a movie. I watched a movie and then today I go on my laptop to work and I left the hard drive in. I'm looking through my folders for some images and accidentally opened the wrong folder. It was a folder of photos and at first glance they looked like my photos (pictures of us, holidays etc.,) so I enlarged the files and saw a photo in there of woman in her underwear. It's not a particularly sexy photo, she's in pretty plain undies getting ready. It's clear that the photo has been taken sneakily from the bed, you can see the foot of the bed and the clothes on it in the photo. It's a WhatsApp file from last year. Its definitely not a meme or anything from the internet. I dont know what to do. He has lots of friends and lots of lads group chats on WhatsApp and I know they send each other 'laddy' things because he shows me most of them so it could be sent from a friend but I'm failing to find a reason why someone would send a pretty plain and personal picture like that. We arent seeing each other over lockdown so dont particularly want to start a fight or have him accuse me of snoopy on him. WWYD?
