I found 15000 image of other women on my partners phone

Me and my boyfriend have been together for 8, we have. 3 year old son together. Our relationship was fantastic to begin but after the birth of our son I feel it went south, I gained around 80lbs that I have struggled to shed due to PCOS and my poor diet (not gunna lie) and our arguing increased. Around 5 years into our relationship he got a new phone and changed his password so I didn’t know it because he did I was too snoopy. I did snoop a bit, but that was just checking all as well - and I knew he used to look at mine too. We had each other’s passwords. So our sex life has been shit as my PCOS has caused me to have a none stop period for months at a time! But before that I felt pushed away, like he didn’t want me any more but when we argued and I asked him to leave he doesn’t. I honestly believe he’s only here for our son, so anyway 5 months ago he got a new phone and cleared his old phone and gave it to me. While he was at work I being me decided to restore his old photos. To my horror there were 15000 images of women, this is not a overestimated amount there were lots of sexy models (fine) but this catalogue included screenshots of his 2 ex girlfriends, some of our female school friends (from years back). Females we know no family friends and even some of his cousin!! When I confronted him he cried but now this has been leaking in my mind that there is something seriously wrong with me, I mean my OH would rather look at 15k other woman then me. It’s really getting to me and has been on my mind all day, I don’t feel our relationship is working, he’s been so distant. Can someone shed light on this. We are month 29 and I’m just heartbroken.

I agree with the first reply in that you should both seek out couples therapy and perhaps also individual therapy

I think you have to decide if you are okay with him just looking at images of women It seems you said some screenshots of 2 exes, old high school friends, cousin? but I'll assume these weren't too many out of the 15000 I would also make sure he is not doing anything other than just looking There is nothing wrong with you, you guys have a kid and need to make time for date nights/ self-care / etc
