Am I the only one?

Am I the only one who wants to be with my SO ALL the time? Like I get sad if I'm away from him for more than like 7 hours. He doesn't get annoyed by it & doesn't think I'm clingy but at the same time idk how to explain this to him. I just love him so freaking much! I wanna be around him all the time 😩 Does anyone else go through this?
