I just don't know anymore (long topic)

My fiancé and I have been together for 2 years. We've gone through a lot together but we've always found comfort in each other. Our sex life is great, and while we do get sexually frustrated every now and then, our sex life is great! However in the past there's always been major problems with him. He would always follow these pages on instagram where the pages would post videos and pictures of women with these enormous boobs either doing sexual things or teasing the camera. I don't have big boobs at all even though I'm already an adult however my bum is a bit bigger then average because I do have a pear shaped body. My small boobs have always been my biggest insecurity despite being my smallest assets lol. So now my problem here is my fiancé since the beginning has told me he loves, adores, and worships my body! But then I find out that he's watching all these animes where the women are extremely sexualized and their enormous boobs are being exposed in just about every single scene! I watch anime, I get it. Women are almost always sexualized but the animes that he watches are basically just hentai! It lowers my self esteem majorly and when I found out about it, it hurt me immensely. I just don't know what to do anymore and honestly I question if I've ever even been good enough for him in the first place. Why tell me you worship my body, including my small breasts, but then go behind my back and watch those kinds of things? We literally just had a talk about this two days ago, he knows how I've been feeling unattractive these past few days and I discovered all the anime/hentai last night and I'm like what the fuck?? Did you just tell me all the stuff you told me the other day to get me to shut up??? I just feel like crap right now and I'm just lost...
