So, I’ve been dating this guy for about 6 months. Nicest guy. Opens the door, pays for meals, sends flowers. Just overall a very nice gentleman. Chalked it up as his sex drive is higher than mine but A little much when he’s turned on but nothing concerning. Well. I decided to google his name the other day for the hell of it. He came back up as a sexual predator for child pornography, offense was 2 years ago. Fully on the list, arrested, the whole thing. I’m so confused, because it doesn’t seem right. I ask him about it and he said he was on a dating site, someone sent photos and they ended up being underage when he clicked the link to download them. He tried to delete them but they were on his hard drive ect. What’s the honest likely hood this is true? I thought that crap was hard to find on the dark web. Not just “accidentally “ downloaded. I ended things immediately. I feel guilty because truly he seemed like an awesome person. Aitah for not believing this story?
