Maybe I’m just a crybaby.. but

Lately I’ve been sending my fiancé nudes we’ve been living separately since May of this year. Before we started living separately he would screenshot nudes I sent him and tell me how much he enjoys them. Since we’ve been living apart I’ll send them he won’t look at them or will not say anything about them. I can’t help but think he doesn’t find me attractive anymore. Since we’ve been living apart he’s started watching hentai and has plenty of screenshots of that. I’ve seen it myself. I’ve asked him why don’t you screenshot what I send you. His excuse is always I’ve got so many nudes of you already. But.. they’re from when I was a bit thinner since I’ve put on a few pounds this year. I can’t help but feel unattractive and upset. I don’t know what else to do. I’ve been trying to lose weight as hard as I can but I’ve pcos so it’s a very rough journey. Losing any weight at all is hard for me. We don’t even sext or send pictures back and forth at all. I’ve told him just because we live apart doesn’t mean we shouldn’t be intimate with each other still and he says he’s still intimate with me but really he’s not. He’s only trying somewhat in person. Any advice?
