Hello everyone, this question is off topic. He recently changed his phone and left the old one at home when he went to work. I took it and saw that it was on some websites (of a sexual nature). I didn't open what was there. And Telegram notifications came from such groups. Now I don't know how to live with this. There's no reason for it, and he never gave me any before. But still, I'm shocked. I understand that he's a man and wants to watch this, but I don't understand the other side. And I can't accuse him, although I never looked into his phone for 3 years of our relationship...
