self consciousness

I just need to rant a little bit. Because it's been bothering me all day/night. Today me and my boyfriend were just cuddling, and I was scrolling through dote( a shopping app) and we were making fun of some of the Victoria secret models. Like their facial expressions, stuff like that. And I noticed one girl looked like she was extremely uncomfortable so I said "wow haha she looks so unhappy!" Mind you she was in a push up bra that made her boobs look like balloons. And my boyfriend. Open mouth smiling was like "well I think they (her boobs) look great😃" then told me he was joking but proceeded to talk about how they were the "perfect size" and my heart sank. This girl had big boobs, or the bra made it seem that way.. I'm only a 34 B.. so him saying that made me wanna burst into tears. He knows I'm extremely self conscious, and he's told me multiple times that he loves my boobs. But seriously... you don't say that.. I literally went into the bathroom and cried.. I feel so gross about my body now, and at this point I don't even want to take off my shirt in front of him anymore. I haven't said a word to him about how I feel. Because to him it was just a joke and it didn't mean anything.
