Issues in “paradise”

I’m probably just being paranoid or something like that but every time I send a photo to my boyfriend he usually hypes me up even if it’s just a goofy photo.. recently he doesn’t say anything at all like he never even saw the photo or whatever..I’ve always been insecure but that’s besides the point it just sorta makes me feel that he doesn’t see me the same anymore or it brings me to the conclusion that maybe he’s cheating and found someone better idk rlly we have talked about it but he just says “it’s nothing don’t worry about it” or “I always say something” but when I show him the screen shots it’s like the photo is ignored..idk I just need some advice 🤷🏻‍♀️
