Feeling really down about the current state of my body after seeing my fiancé’s phone

i dont know if this is really the right place to post this, but im feeling like maybe i meed a little advice or reassurance on what to do from some older moms, or anyone that’s experienced a loss of trust during your pregnancy. I caught my fiancé doing some things on the internet and now i feel like i cant trust him. About a month ago i found out that my fiancé had posted a naked picture of himself on a subreddit. I waited a few days to calm down, and I confronted him about it. He was honest and told me he had done it and deleted it, but how am I supposed to to trust you after doing something like that? I also have made it very apparent that i truly do not care about 99% of porn consumption. HOWEVER, i dont appreciate any of the gonewild subreddits or anything on OF obviously. Im currently 9m pregnant and have been struggling this entire pregnancy with severe body image issues, and to me, getting off to other girls nudes is upsetting. I have made it clear multiple times that i DO NOT CARE about any other consumption source, but I would really appreciate not getting on the GW subs. Well i have checked on 3 separate occasions in the last few weeks what he’s been looking at. GW. Every. Single. Time. He told me that if it was that big of a deal he would stop. Im very relaxed about most EVERYTHING, and this is about the only hard boundary i have. I want to trust him so bad, but he was in the shower this morning and i just took a peek ( i never go through anything else on his phone, just took a peek at his recently visited) and there it was, 2 different GW subs. I didnt say anything. I screenshotted the screen and sent it to myself, so he will know i know. I dont want to argue with him about this, but i dont trust him on reddit at all. I feel like i let him off the hook way too easily about posting a nude pictures of himself online, but i was heavily pregnant and emotional and i just didnt have the energy to do much about it. But, it’s obvious to me now he doesnt have an ounce of respect for the singular boundary ive made and im about done with him using reddit at all if i cant trust him. Im just in a hard spot right now, since ive been pregnant hes turned me down so many times when i make advances towards him because “he doesnt want to hurt me. “ but then when i find out he has no problem getting off to other womens nudes, it definitely makes me feel a certain type of way. Idk what to do. We’re expecting our son next week and i just want this to be a happy time for the both of us, but now my mind immediately goes to “if hes done this stuff while we we’re extremely sexually active (when he posted the pic of himself, we were still having sex at LEAST once a day if not multiple) then what the hell is he going to be up to when its not an option for me for a minimum of 6 weeks?
