Nudes

So me and my best friend are really comfortable with each other (he’s a guy) and we sometimes send nudes but this was my first time sending my boobs ( all I ever sent was ass shots) and now I feel like he looks at me differently. I talked to him about it and he said he doesn’t, maybe it’s the girl in me or maybe it’s because...I’m starting to catch feelings idk. But I hate myself for obsessing over this. Any advice??
