So im very conscious about my body especially my top area to the point i will be having surgery in the near future, this is something i have wanted since i was roughly 16 and after having 2 DC and BF both i feel way more worse than before. But my DP knows this and towards me he has always said I don't need surgery but my problem is that he is on 2 group chats, one with 40+ people in and the second is work friends (who are also in the first one) and in these group chats they send alot of links, pictures and videos of random things, funny stuff and a fair bit of pornographic stuff. He knows I don't like it and says he deletes it when it comes through but I know this isn't the case. When were together he swipes it off the top of the screen, never goes on WhatsApp when at home but as soon as he goes to work he's online most of the day. I've even heard him commenting on some videos before when he's been in the next room saying (some nice big racks she's got) and it broke me. It's made me so low and I don't know what to do. I would rather him come off of these chats but have no idea how to even approach the situation AIBU?
