My partner I’ve noticed is very sneaky with his phone, this has became a lot more apparent during lockdown.. I am generally not a jealous person, I don’t think I’ve looked on his phone for around 3 years (5 years together). A couple of weeks ago my phone died and I needed to call my mum back and my phone was charging. He was very reluctant and wasn’t too happy with giving me it. I rang her and he cut it very short he said he was talking to work mates, I gave him his phone back. Over the past couple of weeks since this I’ve felt something is off, he hid his friends list on Facebook from me (he didn’t have this private before). Thinking I was just being paranoid I left it. He was never this secretive before lockdown. Anyway a few days ago I couldn’t stop thinking he was hiding something so I tried to get on to his Facebook. He knows my password and I am meant to know his, but he had changed it. He’d also changed Instagram and his email password (they were all the same) obviously I wasn’t going to jump to any conclusions as someone could’ve hacked his accounts previously (I know not likely!). He came back off his night shift and I couldn’t help but go on his phone. I discovered he’s been adding a lot of girls on Facebook and liking all of there pictures, one of which a girl who has previously sent him dirty pics of herself before we were together. He sent the woman who took his virginity a friend request too, This was over 7 years ago and he sent it a few months ago... now in my relationships I believe unless you have kids previously then there is no need to contact an ex or someone you’ve previously slept with. I then went into his pictures and found several videos of women touching themselves etc. I know men watch porn , I’m not 100% happy with it but The fact he’s downloaded these videos to his photo albums where pictures of our 3 kids are upsets me. Anyway I confronted him and he deleted the girl who sent him dirty pictures previously and he said he didn’t have her on anything else, she used to live right next to him and had she been a little bit older (she’s about 2 years younger than us) all of his friends/him would’ve slept with her. He said the reason he added her was for extra likes on his pictures, he uploads maybe every 4 months? I asked about his the woman who took his virginity and why he added her he said he couldn’t remember/it wasn’t him. He has added a total of 500 girls in the past few months. I then checked his Instagram the day after and he has the girl who sent the pics on there (he searched for her) and was liking her pictures. He told me he didn’t have her on anything else, clearly he lied. In the past he has stayed out all night from being on a night and back in December time I remember he did just that, apparently with a friend. On his search history he searched for a girl purely to block her... I feel I’m going insane, he’s lying saying he doesn’t remember downloading the porn or adding all these girls.. I’ve always trusted him in the pay and never thought I’d question him but thinking about it he can’t go out now in lockdown and all of a sudden starts pursuing other women?
